Dice tomato and red onion and add to a large tupperware.
Cook ground beef over medium to high heat. Once it is 80% of the way cooked, season with salt, pepper, garlic powder, onion powder, and dried dill. Let it fully cook.
Drain any excess fat off the ground beef and let it cool slightly. Add to tupperware with veggies.
Add feta and chopped dill to the filling.
Heat up a whole wheat pita in the microwave for 5-7 seconds. Slice it in half and make a pita pocket with it.
Add 2-3 Tbsp tzatiki into each side. Stuff pitas with ground beef mixture (I use about ¼ of the filling per serving).
