Creating Chicken Gyros is a simple process when you follow these steps:

1. Prepare Marinade: In a large bowl, mix olive oil, Greek yogurt, minced garlic, oregano, cumin, paprika, salt, pepper, and lemon juice.
2. Add Chicken: Place the chicken thighs into the marinade and ensure they are completely coated. Cover the bowl, and let it marinate in the refrigerator for at least 1 hour (or overnight for best results).
3. Preheat Grill or Skillet: Preheat your grill or a large skillet over medium-high heat.
4. Cook Chicken: Remove the chicken from the marinade, letting the excess drip off. Cook for about 6-7 minutes per side until fully cooked and juices run clear.
5. Rest Chicken: Once cooked, remove the chicken from the heat and let it rest for a few minutes before slicing.
6. Slice Chicken: Thinly slice the cooked chicken thighs into strips.
7. Warm Pita: If desired, warm the pita bread briefly on the grill or in a skillet.
8. Assemble Gyros: Place a generous amount of sliced chicken in the center of each pita. Top with diced tomatoes, shredded lettuce, red onion, cucumber, and tzatziki sauce.
9. Fold Pita: Fold the pita over the filling and secure it with a piece of parchment paper or foil if needed.
10. Serve: Enjoy your delicious homemade Chicken Gyros immediately!

By following these steps, you’ll create Chicken Gyros that are bursting with flavor and perfect for any occasion.
