Follow these easy steps to create your delicious Turkish Chicken Kebabs:

1. Prepare the Marinade: In a large bowl, combine olive oil, yogurt, lemon juice, minced garlic, paprika, cumin, coriander, oregano, salt, and black pepper. Mix well.

2. Cut the Chicken: Cut the chicken thighs into 1.5-inch pieces and add them to the marinade. Toss until the chicken is evenly coated. Cover and refrigerate for at least 30 minutes, or up to 4 hours for more flavor.

3. Prepare the Vegetables: While the chicken is marinating, cut the bell peppers and red onion into large chunks.

4. Preheat the Grill: Preheat your grill to medium-high heat. If using a grill pan, heat it over medium-high heat on the stovetop.

5. Assemble the Skewers: Thread the marinated chicken pieces onto the skewers, alternating with pieces of bell pepper and onion.

6. Grill the Kebabs: Place the skewers on the hot grill. Cook for about 15-20 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks.

7. Check for Doneness: Ensure the internal temperature of the chicken reaches 165°F (75°C) for safety.

8. Rest the Kebabs: Once cooked, remove the skewers from the grill and let them rest for a few minutes before serving.

9. Garnish: Optionally, drizzle with extra lemon juice or sprinkle with fresh parsley for added flavor.
