Preparation
1. Cut pineapple in 6 crosswise slices, set aside
2. For marinade, combine dressing, sugar, juice, and soy sauce. In large, shallow non aluminum baking dish or plastic bag, add chops and 2/3 cup marinade; turn to coat. Cover, or close bag, and marinate in fridge 3 to 24 hours, turning occasionally. Refrigerate remaining marinade.
3. Remove chops, discarding used marinade. Grill or broil, basting frequently with refrigerated marinade, until chops are done. While chops are cooking, grill or broil pineapple slices until golden and heated through.
