Creating Chicken Gyro Bowls is simple and enjoyable. Just follow these steps:

1. Marinate the Chicken: In a large bowl, combine olive oil, red wine vinegar, lemon juice, minced garlic, oregano, cumin, paprika, salt, and pepper. Add the chicken thighs, ensuring they are well coated. Cover and marinate for at least 30 minutes.

2. Prepare the Tzatziki Sauce: In a separate bowl, mix Greek yogurt, grated cucumber, minced garlic, lemon juice, salt, and pepper. Stir until well combined. Refrigerate until ready to serve.

3. Cook the Chicken: Heat a grill pan or skillet over medium-high heat. Remove chicken from marinade and cook for about 6-7 minutes on each side or until fully cooked and no longer pink in the center. Remove from heat and let rest for a few minutes.

4. Slice the Chicken: Once rested, slice the chicken into strips.

5. Prepare the Bowls: In serving bowls, place a generous portion of cooked rice or quinoa as the base. Top with sliced chicken, diced cucumber, diced tomato, sliced red onion, cherry tomatoes, and crumbled feta cheese.

6. Add Tzatziki Sauce: Drizzle tzatziki sauce generously over each bowl.

7. Garnish and Serve: Finish with fresh parsley for garnish. Serve immediately while warm.
