Creating the Turkish Chicken Kebab can be easy if you follow these simple steps:

1. Prepare Marinade: In a bowl, mix olive oil, yogurt, lemon juice, minced garlic, cumin, paprika, oregano, salt, and pepper until well combined.
2. Marinate Chicken: Add the chicken cubes to the marinade. Ensure all pieces are well coated. Cover and refrigerate for at least 1 hour, preferably overnight for maximum flavor.
3. Soak Skewers: If using wooden skewers, soak them in water for about 30 minutes to prevent burning during grilling.
4. Preheat Grill: Heat your grill to medium-high heat.
5. Skewer Chicken: Thread the marinated chicken onto the skewers, alternating with bell peppers and onions if desired.
6. Grill Kebabs: Place the skewers on the grill. Cook for about 10-15 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks.
7. Check Doneness: Use a meat thermometer to ensure the internal temperature of the chicken reaches 165°F (75°C).
8. Rest: Once cooked, remove the kebabs from the grill and let them rest for a few minutes.
9. Serve: Your Turkish Chicken Kebabs are now ready to enjoy!
