In a large bowl, combine ground beef, parsley, onion, and garlic. Add spices and mix thoroughly until well incorporated.

Cut pita breads in half to form pockets, fill each with beef mixture, packing gently.

Brush stuffed pitas with olive oil and grill or cook in skillet for 7-8 minutes per side, until crispy and golden.

Let pitas rest for 5 minutes, then slice and serve with sides like salad or hummus.
