I love hamburgers and tropical fruit, so it just seemed natural for me to combine them. My family frequently requests this unique Hawaiian pineapple burger recipe. It's a nice change of pace! —Joi McKim-Jones, Waikoloa, Hawaii
Drain pineapple juice into a small bowl; add teriyaki sauce. Place 3 tablespoons in a shallow dish. Add pineapple slices; turn to coat and set aside.
Shape beef into 4 patties; place in an 8-in. square baking dish. Pour the remaining teriyaki sauce mixture over patties; marinate for 5-10 minutes, turning once.
Remove burger patties from marinade; discard marinade. Grill, covered, over medium heat or broil 4 in. from the heat for 6-9 minutes on each side or until a thermometer reads 160°. Meanwhile, in a small skillet, saute onion in butter until tender, about 5 minutes; set aside.
Remove pineapple slices from marinade; discard marinade. Place pineapple on grill or under broiler to heat through. Layer bottom buns with lettuce and onion. Top with burgers, cheese, pineapple and bacon. Replace tops.
