In a large bowl, mix the ground meats with salt, pepper and cumin. Chop the onions and parsley in a food processor, then add them to the ground meat, mixing well.
450 g ground beef, 2 onions, 50 g parsley, 1 tsp salt, 1 tsp cumin, 1/2 tsp black pepper, 150 g ground lamb
Cut each pita in half and fill the halves with the ground meat mixture, then press them well: you want the arayes to be well stuffed but not too thick, otherwise the meat will not cook thoroughly. Aim for 2.5 cm of thickness, not more.
3 pitas
Brush a little oil on both sides of your arayes and heat the grill in the meantime. If you have a BBQ like I do, use it without hesitation. If not, heat a normal grill pan and preheat the oven to 350° F.
50 ml extra virgin olive oil
When the grill is hot, arrange the arayes on the grill and cook them until they are golden and a little scorched on the outside, about 2-3 minutes per side.
At this point, if you have a BBQ transfer the arayes to the less hot part of the BBQ and let them cook for another 5 minutes. If you are cooking in your kitchen, transfer the arayes to the oven and let them cook for about 10 minutes, or until the meat looks done.
