In a large bowl, combine ground beef, feta, garlic, olive oil, parsley, salt, garlic powder, onion powder, paprika, cumin, coriander, cayenne, cinnamon, and dried mint. Mix thoroughly with your hands until well combined. Shape the mixture into 8 equal small patties.

Cut each pita bread in half to create pockets. Stuff each pita half with two meat patties and any additional desired vegetables or toppings.

Preheat a skillet over medium heat. Lightly oil the skillet if needed. Cook the stuffed pitas for 4-5 minutes on each side until crispy and cooked through, making sure to sear the open side of each meat patty.

Serve hot with lemon wedges and optional tzatziki dip.
