To a small mixing bowl, add egg, garlic, ginger, turmeric, ground coriander, cayenne pepper, salt, and black pepper. Mix thoroughly with a fork.
To a large mixing bowl, add the ground turkey, the egg and spice mixture, the parsley, and the breadcrumbs. Using your hands or a large fork, mix to thoroughly combine.
Make small meatballs that are about an inch in diameter.
Yogurt Sauce
To a small bowl, add the yogurt, the lemon zest, and the lemon juice. Add in half the chopped parsley. Mix and then add salt and fresh ground pepper to taste.
Cook and Assemble
Preheat a nonstick pan to medium heat. In batches, cook the meatballs and brown on all sides until all the meat it fully cooked.
For the pitas, heat a large skillet coated in oil to medium-low heat and cook on both side for a few minutes until fully warmed.
Open the Pita Pocket, add the hummus, then the meatballs, top with yogurt sauce and parsley, and enjoy!
