In a bowl, mix the Greek yogurt, olive oil, lemon juice, and all the spices into a marinade.
Toss in the chicken, coat it well, and marinate for at least 1 hour (overnight is better).
Preheat a skillet over medium-high heat. Add the chicken and cook for 5–7 minutes per side or until browned and cooked through.
Let the chicken rest for 5 minutes, then slice thin.
Serve in warm pita or flatbread with your favorite toppings and sauce.
