Creating delicious Turkish chicken kebabs is straightforward if you follow these steps:

1. Prepare the Chicken: Cut the chicken thighs into 1-inch cubes and set aside.
2. Make the Marinade: In a bowl, whisk together the olive oil, yogurt, lemon juice, minced garlic, cumin, paprika, coriander, oregano, salt, black pepper, and cayenne pepper.
3. Marinate the Chicken: Add the chicken cubes to the marinade, ensuring they are well coated. Cover and refrigerate for at least 30 minutes or up to 4 hours for maximum flavor.
4. Prepare the Skewers: If using wooden skewers, soak them in water for 30 minutes to prevent burning. If using metal skewers, you can skip this step.
5. Skewer the Chicken: Thread the marinated chicken onto the skewers, leaving a little space between each piece for even cooking.
6. Preheat the Grill: Heat your grill to medium-high heat (about 400°F or 200°C).
7. Grill the Kebabs: Place the skewers on the grill and cook for 15-20 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks.
8. Check for Doneness: Ensure the internal temperature of the chicken reaches 165°F (75°C).
9. Rest the Kebabs: Remove the kebabs from the grill and let them rest for a few minutes to retain their juices.
10. Garnish and Serve: Sprinkle fresh parsley on top and serve with lemon wedges for an extra burst of flavor.
