To a large bowl, add the ground beef, crumbled feta, garlic, olive oil, all the spices and parsley and mix together with your hands until combined. Form 8 equal half moon shaped thin 'patties'. Cut the pitas in half, fill with the meat patties and spread out evenly.
Preheat a skillet over medium heat and add in a drizzle of olive oil. Cook the arayes for 4-5 minutes per side, or until the meat is cooked through. Don't forget to sear the open meat side too! Make sure to keep the heat on medium or medium low.
Notes
