1 lbs. boneless chicken breast
¼ cup mozzarella cheese, shredded, divided
1 tsp. butter
¼ cup Franks Hot Sauce
¼ tsp. celery salt
Preheat grill to medium-low heat
Cut your chicken horizontally but not all the way through. Sprinkle the inside of the chicken with pepper. Evenly top the chicken with cheese and fold over the chicken to close it.
In a microwave-safe bowl melt the butter for 8 seconds. Stir in hot sauce and celery salt.
Brush one side of the chicken with hot sauce mixture and place the hot sauce size down on the grill. Brush more hot sauce over top of chicken. Cook for about 7 minutes. Flip the chicken and brush on remaining hot sauce and cook until no longer pink; about 5 minutes more.
