Place the chicken breasts in the resealable bag, close and give it a good massage to coat with the marinade. Refrigerate for 30 minutes or up to overnight.
When ready to cook, turn on the broiler and place the rack in the middle position. Place the marinated chicken breasts on a foil-lined baking sheet and spoon some of the chunky pineapple/ginger from the marinade on top of the breast. It will help keep the chicken moist. Broil for 8 to 10 minutes on each side, for a total of 16-20 minutes. Discard any remaining marinade in the bag.
While the chicken is broiling, heat the reserved teriyaki sauce (that you had previously set aside in step 1) in a saucepan. Bring to a simmer and cook for 3 minutes or until thickened slightly. When chicken is done, Slice the chicken, pour the teriyaki sauce over top and serve immediately.
