In a bowl, whisk together Greek yogurt, lemon juice, red wine vinegar, olive oil, minced garlic, paprika, cumin, cinnamon, oregano, thyme, coriander, salt, pepper, and dried mint. This aromatic marinade will infuse the chicken with herby, tangy flavors.

Coat the chicken thighs or breasts thoroughly with the marinade. Cover and let it sit in the refrigerator for at least 1 hour, preferably 4 hours or overnight for maximum flavor and tenderness.

Grill, pan-fry, or broil the marinated chicken until fully cooked through and nicely charred on the outside. The chicken should be juicy, smoky, and tender, with a flavor packed into every bite. Rest briefly before slicing.

Dice cucumbers, tomatoes, and red onion. Crumble feta cheese and chop fresh herbs like dill and parsley. These fresh toppings will add coolness, crunch, and herby aroma to your gyros.

Warm pita bread until soft and crispy. Spread some yogurt or tzatziki inside. Add slices of cooked chicken and top with fresh vegetables, feta, and herbs. Wrap tightly and serve immediately, enjoying the juicy, herby, and vibrant flavors.
