Steps
1. In a bowl, combine Greek yogurt, lemon juice, minced garlic, dried oregano, salt, and black pepper.
2. Place the chicken breast in the marinade, ensuring it is coated on all sides. Cover and refrigerate for at least 30 minutes, or overnight for maximum flavor.
3. Preheat grill to medium-high heat.
4. Remove chicken from marinade and discard excess marinade. Grill the chicken for 6-8 minutes per side, or until cooked through and juices run clear.
5. Let the chicken rest for a few minutes before slicing. Serve hot.
