Place the chicken in a large bowl. Pour the bottle of Italian dressing all over the chicken. Cover bowl and place in fridge to marinate for at least 3 hours or up to overnight.
When ready to grill the chicken, discard the dressing. Heat the grill to medium heat (around 350 degrees F.) Grill chicken for 4 to 5 minutes on each side or until internal temperature of chicken reaches 165 degrees F. Serve and enjoy!
