In shallow dish, whisk together egg, Ranch dressing, flour and ground pepper. Mixture will be thick and glue-ish. Depending on actual egg size, you may need to thin with another tablespoon or so of Ranch dressing.
Add cheese crackers, crispy jalapenos, garlic powder and Instantly Fresh Cilantro to heavy-duty gallon-capacity zip-top bag. Use rolling pin to crush contents into medium-coarse crumbs.
Taking one tender at a time, dredge in egg mixture and then shake in crumb mixture until coated. Place on rimmed baking sheet that has been coated with cooking spray, or for even more crispness, use a mesh baking tray on top.
Bake at 390 F degrees for 20 minutes, or until cooked through at thickest portion of tender. If placed straight on the baking sheet, flip tenders once after 10 minutes of baking. If using a raised mesh tray, no need to flip.
Remove tenders from oven, let cook for 3 minutes, garnish with jalapeno slices and cilantro, and serve with a bowl of Homestyle Ranch Dressing for dipping.
