My favorite burger is the Red Robin Banzai Burger. It's basically a teriyaki burger with pineapple. I found a copy cat recipe for it, so now I can make it at home!
adapted from recipegoldmine.com
1 1/3 pounds ground hamburger meat
8 pineapple rings
2 cups teriyaki sauce (divided into 2 separate bowls)
4 slices Cheddar cheese
4 sesame buns
4 TBSP mayonnaise
8 slices tomato
1 cup shredded lettuce
1. Form round burger patties. Marinate burger patties in bowl #1 of teriyaki sauce for 30 minutes; turning patties over half way through. Marinate pineapple rings in bowl # 2 of teriyaki sauce for 30 minutes; turning rings over half way through.
2. Remove burger patties from marinade and grill on high heat to desired doneness. Baste with teriyaki sauce while grilling, if desired. Melt Cheddar cheese on top of patties while still on grill pan by covering with lid. Grill pineapple rings on medium heat for 1 minute on each side.
3. Toast buns to prevent sogginess. Spread mayo on both halves of the buns.
4. To assemble burger, place the hamburger patty with cheese on bottom bun, followed by 2 tomato slices, 2 pineapple rings 1/4 c shredded lettuce, and last of all the top bun.
Makes 4 burgers.
