Steps
1. In a bowl, combine yogurt, cumin, coriander, paprika, turmeric, cinnamon, garlic, olive oil, salt, and pepper.
2. Add chicken slices to the marinade, cover, and refrigerate for at least 30 minutes.
3. Heat a skillet over medium heat and cook the marinated chicken for 6-8 minutes until cooked through and slightly charred.
4. Warm the pita bread in the skillet or oven.
5. Plate the cooked chicken, drizzle with garlic sauce, and serve with chopped cucumber, tomato, and parsley.
6. Optionally, wrap the chicken and vegetables in the pita for a traditional shawarma experience.
