1. To make the teriyaki sauce, place the crushed pineapple, soy sauce, honey, ginger and garlic a bowl, whisk to combine. Pour half of the teriyaki sauce in a resealable plastic bag and reserve the other half. 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. (I refrigerated for overnight for fuller taste)
3. 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.
Keeping the chicken in the marinade overnight will make it even tastier
