In a large bowl, mix together the ground chicken, all the spices, garlic, lemon juice, ginger and green onions. Use your hands to score into 4 patties and and form into burgers.
Heat a skillet or grill (I drizzle oil on the skillet) and cook burgers on each side until cooked through, about 3-4 min each side.
To make the yogurt sauce, mix all ingredients together in a bowl. (Sometimes I had finely chopped cucumber as well).
To assemble the burgers: Place burger on pita bread and top with tomato slice, fresh mint pr cilantro or parsley and dollop of yogurt sauce.
