Roll the damp chicken breasts in the Ranch salad dressing mix until they are well coated.

Sprinkle the chicken breasts with salt and pepper to taste.

Place the coated chicken breasts in a shallow dish and marinate them in the refrigerator for at least 1 hour.

Preheat the grill to medium-high heat.

Remove the chicken breasts from the marinade and discard any excess.

Grill the chicken breasts for 10 to 12 minutes, or until they are no longer pink in the center and the juices run clear, turning them halfway through cooking.

Once cooked, remove the chicken breasts from the grill and let them rest for a few minutes before serving.

Serve hot and enjoy the zesty ranch flavor!
