- 1 1/2 cups lemon-lime soda
- 1/2 cup olive oil
- 1/2 cup soy sauce
- 1/4 teaspoon garlic powder
- 4 (6 ounce) skinless, boneless chicken breast halves
- Whisk lemon-lime soda, olive oil, soy sauce, and garlic powder in a bowl and pour into a resealable plastic bag. Add chicken breasts, coat with the marinade, squeeze out excess air, and seal the bag. Marinate in the refrigerator overnight.
- Preheat grill for medium heat and lightly oil the grate.
- Remove chicken from marinade and discard used marinade. Cook chicken breasts on preheated grill until no longer pink in the center and the juices run clear, 7 to 8 minutes per side. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
