6 boneless, skinless chicken breast halves, (about 1-1/2 lbs.)
Pour 1/2 cup Wish-Bone® Italian Dressing over chicken in large, shallow nonaluminum baking dish or plastic bag. Cover, or close bag, and marinate in refrigerator, turning once, up to 3 hours.
Remove chicken from marinade, discarding marinade. Grill or broil chicken, turning once and brushing frequently with remaining dressing, until chicken is thoroughly cooked. Serve on rolls and garnish, if desired, with lettuce.
