Quick, Easy Low-carb Sandwich Salad Fillings – Tuna, Chicken and Egg

When it comes to meal prepping or throwing together a quick lunch, sandwich salad fillings are a lifesaver. Whether you’re in a hurry or just want something simple and satisfying, these protein-packed, low-carb mixtures can be served in all kinds of ways—on bread, tucked into lettuce wraps, or scooped over greens. Bonus: they rely on pantry staples, are easy to customize, and can double as a snack or main meal!

Let’s talk about three go-to classics—tuna salad, egg salad, and chicken salad—but with a little twist. These versions are anything but boring, loaded with flavor and built to nourish.

Spice up lunch with these flavorful Southwest Cottage Cheese Egg Salad. Thanks to cottage cheese, it offers more protein with less fat than a traditional recipe. With a zesty lime kick and great nutrition, this quick meal - use in a tortilla wrap, fix up a sandwich, pile on a salad, or stuff into a scooped-out tomato or cucumber.

🥚 Southwest Cottage Cheese Egg Salad:  Egg salad gets a macro-friendly makeover with this creamy, zesty twist featuring cottage cheese instead of mayo. The result is rich in protein, low in carbs, and packed with satisfying flavor thanks to a southwestern spice blend and optional add-ins like salsa or chopped veggies.

  • Meal idea: Spoon it into avocado halves, pile it on cucumber rounds, or enjoy over a simple spring mix salad.
  • Pantry staples used: Eggs, cottage cheese, salsa, spices
  • Custom add-ins: Jalapeños, black olives, fresh cilantro, hot sauce

🐟 Asian-Inspired Tuna Salad: This isn’t your basic tuna salad. Think unhinged (but healthy) flavors: soy sauce, sesame, and a kick of chili garlic sauce bring this pantry-friendly protein to life. Instead of bread, it’s sandwiched between crisp cucumber slices for a refreshing, low-carb bite.

  • Meal idea: Serve in a hollowed out cucumber – low-carb sandwich style. Or serve on a bed of shredded cabbage, baby spinach or even broccoli slaw.
  • Pantry staples used: Canned (or pouch) tuna, sesame oil, soy sauce, chili sauce
  • Custom add-ins: Sriracha, edamame, green onion, avocado
A light and fresh chicken salad made summery with fresh cherries -- and given a great texture with quinoa and pecans. No-mayo, a dressing of yogurt and lime juice.

🍒 Cherry Chicken Salad with Quinoa & Pecans: This chicken salad skips the mayo and adds a sweet-savory punch with dried cherries, crunchy pecans, and a tangy vinaigrette. It’s hearty enough to keep you fueled for hours, thanks to a protein boost from chicken and optional quinoa.

  •  
  • Meal idea: Spoon it into a hollowed bell pepper, serve in lettuce cups, or make a mason jar salad layered with greens on the bottom.
  • Pantry staples used: Canned, chopped rotisserie chicken or meal-prepped shredded chicken breast, dried fruit, vinaigrette
  • Custom add-ins: Celery, red onion, goat cheese, chopped apples

Pro Tips to Customize Your Salad Fillings:

  • Go Greek: Swap in Greek yogurt or cottage cheese for creamy texture and extra protein.
  • Spice It Up: Use everything bagel seasoning, curry powder, or smoked paprika to change the vibe.
  • Add Crunch: Nuts, seeds, and diced crunchy veggies like bell peppers or pickles add texture.
  • Switch Proteins: These same flavor combos work well with canned or pouch salmon, shredded turkey, or even tofu for a plant-based twist.

These quick and easy sandwich salad fillings prove you don’t need a lot of time—or fancy ingredients—to eat well. Keep them in your rotation for healthy lunches, high-protein snacks, or even lazy dinners when cooking feels like too much. Whether scooped into a wrap, stuffed in a pita, or simply eaten with a fork straight from the bowl (no judgment), they’ve got your back.

Tuna – A high-quality, lean protein rich in omega-3s to support heart and brain health. It’s also a great source of vitamin D, selenium, and B vitamins. I like the Safe Catch brand because they have the lowest mercury levels of any can/pouch tuna on the market.

Edamame – These green soybeans are protein-rich and full of fiber, iron, and antioxidants. They help keep you full longer, support digestion, and offer a satisfying bite. I always have a pack of frozen shelled edamame on hand.

Peanut Butter or Nut Butter – Adds creaminess and depth to the dressing, along with heart-healthy fats, plant-based protein, and a dose of vitamin E. Almond, cashew, or sunflower butter all work, depending on your dietary needs. I’ve been loving this peanut butter.

Cucumber – Crisp, hydrating, and naturally low in carbs and calories. Cucumbers provide texture, volume, and electrolytes, especially helpful after a sweaty workout.

Lime, Garlic, Ginger, Soy Sauce or Coconut Aminos, Sriracha, Sesame Oil – These bring bold flavor without loading on sugar or excess calories. Use coconut aminos to keep it paleo/gluten-free.

🕒 When to Eat It:

  • After a workout, when you want something fresh, fast, and protein-packed
  • For a quick and easy weekday lunch—no microwave or oven required

Air Fryer Parmesan Mushrooms: Crave-worthy and Quick

Looking for an easy, delicious way to enjoy mushrooms? These Air Fryer Parmesan Mushrooms are packed with earthy, umami-rich flavor and take just 10 minutes start to finish. All you need to do is slice up white mushrooms, toss them with olive oil, seasonings, and a touch of freshly grated Parmesan cheese—then let the air fryer do its magic.

Not only do these mushrooms make a fantastic side dish or snack, but they’re also perfect for topping burgers, pizzas, salads, or tossing into pasta for a flavor boost without the fuss.

Pro Tips for the Best Air Fryer Mushrooms:

These easy Air Fryer Parmesan Mushrooms are ready in 10 minutes or less! A healthy, low-carb snack or side dish with bold umami flavor—perfect on their own or added to burgers, pizza, or pasta.
  1. Mushroom Variety – White mushrooms (aka button mushrooms) are easy to find and affordable, but you can also use baby bella (cremini) mushrooms for a deeper flavor.
  2. Oil Options – Use a high-quality extra virgin olive oil for richness, or swap in coconut or avocado oil. For a more indulgent twist, melted butter works too.
  3. Cheese Matters – Freshly grated Parmesan delivers the most flavor (I love my micro planer / grater tool for this), but if you’re in a pinch, the classic green bottle of grated parm will do.
  4. Seasoning Ideas – Keep it simple with garlic powder, salt, pepper, and a splash of soy sauce—or get creative with truffle salt, chili flakes, Italian herbs, or a dash of red wine for added depth.

Once you try these air fryer mushrooms, you’ll want to keep a batch on hand all week long. Batch serves two, making it perfectly sized for a smaller “drawer style” air fryer – but I often use my oven-style air fyer and make a double batch. Quick, crave-worthy, and incredibly versatile!

Easy Mediterranean Baked Feta with Olives and Tomatoes

Need a fast, flavorful appetizer that looks fancy but takes almost no effort? Mediterranean Baked Feta is your answer! This dish is basically a “dump and bake” dream: just toss a handful of ingredients into a skillet or baking dish and let the oven do the heavy lifting. In just about 20 minutes, everything bubbles into warm, briny, melty perfection — the kind of thing you can serve straight out of the pan with a basket of pita chips or crusty bread.

It’s also one of those better-for-you appetizers that feels indulgent but sneaks in plenty of good-for-you ingredients. Tomatoes burst with natural sweetness and bring a punch of vitamin C and antioxidants. Garlic-stuffed olives * deliver a double-whammy of flavor and heart-healthy monounsaturated fats, not to mention a dose of gut-friendly fermented goodness  And olive oil? It’s liquid gold — rich in polyphenols and a cornerstone of the Mediterranean diet for good reason.

*Use any type of stuffed olive you prefer (like pimento or cheese) or black olives, or a mix!

Feta cheese adds the creamy, tangy contrast that ties it all together. Unlike many cheeses, feta is traditionally made from sheep’s or goat’s milk, giving it a slightly lower fat content and a unique, salty flavor that holds up well to heat. It softens and browns in the oven (or grill!), making it scoopable and spreadable — a total crowd-pleaser whether you’re hosting a summer patio party or pulling together something cozy for a winter happy hour.

This dish works beautifully as a warm dip with pita chips, crostini, naan, or hearty crackers — or even spooned over grilled chicken or tossed into pasta for a no-fuss dinner. And yes, if it’s too hot to turn on the oven, you can absolutely throw the cast-iron skillet right onto the grill for an al fresco appetizer that’s ready in minutes.

Whether you’re feeding a crowd or just need something quick and craveable, this Mediterranean Baked Feta is about to become your new go-to. Trust me — it’s the kind of dish that disappears fast and earns you instant favorite-guest status!
