In a mixing bowl, combine turkey, bread crumbs, pepper, onion, ginger, 1/4 cup reserved juice from pineapple and salt. Divide turkey mixture into 4 equal parts and form into patties. Grill, broil or cook in a frying pan over medium until cooked through. The last few minutes of cooking, place pineapple over heat to grill. Place a slice of Swiss cheese on top of each patty when warm. Spread Teriyaki sauce and light mayonnaise on buns and top with burgers and pineapple.
