This works best if you have a hamburger press, but hands work well, too.
1 ¼ pounds ground chuck
1 can pineapple rings
8 strips of bacon
1 bottle teriyaki marinade
Divide meat into 4 equal patties. Press pineapple ring into each patty using a press or your hands. Wrap bacon around the outside edge of the patties, using toothpicks to secure. Put all 4 patties into a Ziploc bag with the marinade and soak for several hours before grilling. Serve on buns with barbecue sauce.
