Combine minced garlic, ground cumin, ground coriander, smoked paprika, ground turmeric, ground cinnamon, chili powder, olive oil, salt, and pepper in a bowl. Mix thoroughly to create a marinade.
Place the thinly sliced chicken thighs into the marinade, ensuring they are well coated. Cover and refrigerate for a minimum of 2 hours, or for even better results, marinate overnight.
Preheat your grill or barbecue to medium-high heat.
Thread the marinated chicken slices onto either metal skewers or wooden skewers that have been soaked in water for approximately 30 minutes.
Grill the chicken skewers for about 12-15 minutes, turning them occasionally until they are fully cooked and display a delightful char on the edges.
While the chicken is grilling, gently heat the pita bread or flatbreads on the grill or in a dry frying pan.
Once the chicken is cooked, remove it from the skewers.
To assemble, lay a warm pita bread on a plate. Arrange slices of grilled chicken, thinly sliced red onion, fresh lettuce, and tomatoes on top.
Drizzle with natural yogurt or tahini sauce.
Fold the pita bread over the filling to create a kebab wrap.
Serve your scrumptious Chicken Donner Kebabs promptly.
