Rub boneless, skinless chicken breast halves with cup of the barbecue sauce. Place in a sealed container and refrigerate overnight.
To cook chicken: Grill over medium-high coals on both sides until done, about 15 minutes or so. (Or place under oven broiler for about 20 minutes.) Reserve on a plate and allow to cool completely (refrigerated).
To make salad: Cut chicken into cubes. Combine chicken, pasta, peppers and onion in a large bowl.
In a separate small bowl, combine remaining cup barbecue sauce, honey and balsamic vinaigrette dressing. Whisk together well.
Pour dressing over chicken mixture and mix together well.
