Mix together the lamb, onion, garlic, eggs, olives, salt, oregano and cumin. When well mixed, gently fold the feta cheese into the mixture and season with salt and pepper. Form the meat into four patties.

Heat the oil in a medium saute pan over medium-high heat and when shimmering, cook the patties for about 4 to 5 minutes on each side or until cooked to your desired degree of doneness.

Serve each burger tucked in the pita pockets or na’an with a tomato slice. Top each burger with a good tablespoon of tzatziki.
