Instructions:
1. Marinate the Chicken:
– In a bowl, whisk together olive oil, red wine vinegar, oregano, garlic powder, onion powder, paprika, salt, and pepper.
– Add the chicken to the marinade, ensuring it’s well-coated. Cover and refrigerate for at least 1 hour (or up to overnight for more flavor).
2. Make the Tzatziki Sauce:
– In a mixing bowl, combine Greek yogurt, grated cucumber, minced garlic, olive oil, dill, lemon juice, and salt. Mix well and adjust seasoning to taste.
– Refrigerate the tzatziki sauce until ready to use.
3. Cook the Chicken:
– Preheat a grill or skillet over medium-high heat. Remove the chicken from the marinade and cook for about 6-7 minutes on each side, or until cooked through and the internal temperature reaches 165°F (75°C).
– Let the chicken rest for a few minutes, then slice it into strips.
4. Assemble the Gyros:
– Warm the pita bread or flatbreads on the grill or in a skillet for a minute.
– Layer the sliced chicken, tomatoes, red onion, lettuce, and feta cheese (if using) on the pita.
– Drizzle with tzatziki sauce and wrap it up.
5. Serve:
– Serve your Greek chicken gyros immediately, with extra tzatziki on the side if desired.
