1. 1. In a bowl, mix Greek yogurt and Greek seasoning together to create the marinade.

2. 2. Add the chicken to the marinade, ensuring it is fully coated. Cover and refrigerate for at least 1 hour, or overnight for best results.

3. 3. Preheat the grill or oven to medium-high heat. Remove the chicken from the marinade and shake off excess marinade.

4. 4. Grill or bake the chicken until cooked through, about 25-30 minutes, flipping halfway through cooking.

5. 5. Serve hot with your favorite sides and enjoy!
