Thaw 1/2 cup frozen raspberries (keeping juices in bowl) and mash together with 1 Tbsp. chia seeds. Let set up for 10 minutes.
Meanwhile, stir together 2 cups Greek yogurt with 1/3 cup peanut butter powder until smooth.
Place raspberry mixture in a sandwich bag, snip end off corner and squeeze into swirled design on top. Or, just dollop on top if you don't need to be fancy.
Serve with apple slices, cinnamon pita chips, jicama sticks or whatever else floats your boat!
