In a bowl, sprinkle chicken with Ranch seasoning mix. Place in a Glad® Zipper Gallon Storage Bag pressing the air from the bag before sealing. Marinate refrigerated for 2 hours.
Prepare the grill using Kingsford® Charcoal, until briquets are evenly ashed over or preheat a gas grill to medium heat. Lightly oil grill grates. Place chicken breasts on the grill, discard any juices. Cook the chicken covered until an instant-read thermometer inserted in the center registers 165ºF, about 6–10 minutes per side. Remove from grill, allow to rest covered for 10 minutes.
In a small saucepan, combine Ranch dressing, garlic and basil. Heat sauce over medium heat. Do not boil.
Pour sauce over chicken and serve.
Substitute pork chops or steak for chicken breasts.
Make ahead: Make a double recipe and use the chicken and sauce to add to salads, pasta or sandwich wraps for a weekday meal.
