Follow these steps to create delicious Mediterranean Chicken Gyros with Creamy Feta Tzatziki:

1. Marinate the Chicken: In a bowl, combine olive oil, lemon juice, minced garlic, oregano, paprika, salt, and pepper. Add the chicken thighs and coat well. Cover and let marinate for at least 30 minutes.

2. Prepare the Tzatziki: In another bowl, mix Greek yogurt, crumbled feta, grated cucumber, minced garlic, lemon juice, salt, and pepper. Stir until well combined and set aside in the refrigerator to chill.

3. Cook the Chicken: Heat a grill pan or skillet over medium-high heat. Add the marinated chicken thighs and cook for about 5-7 minutes per side or until fully cooked through and juices run clear. Remove from heat and allow to rest for a few minutes.

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

5. Warm the Pita: Lightly toast the pita bread on a skillet or in the oven until warm and pliable.

6. Assemble the Gyros: Place warm pita on a plate. Add several slices of chicken, followed by cherry tomatoes, shredded lettuce, and red onion.

7. Add Tzatziki: Generously drizzle the Creamy Feta Tzatziki over the top of the assembled gyros.

8. Garnish: Sprinkle chopped parsley on top for freshness.

9. Serve Immediately: Enjoy your Mediterranean Chicken Gyros with Creamy Feta Tzatziki hot.
