In a large mixing bowl, combine ground beef, parsley, onion, garlic powder, cumin, paprika, salt, and pepper until well incorporated.

Cut pita bread in half to create pockets. Fill each pita with the beef mixture, pressing down to flatten.

Preheat your grill or skillet over medium heat. Cook stuffed pitas seam-side down for 3-5 minutes on each side until golden brown and crispy.

Remove from grill, let sit for a minute, and then slice each pita in half to serve warm.
