Red Robin's Banzai Burger

Red Robin's Banzai Burger

2 lbs ground round

1 bottle Teriyaki sauce (recommend Kikkoman's Teriyaki Takumi Collection - Original )

sliced fresh pineapple 

Sliced cheddar cheese

shredded head lettuce

1 tomato, thinly sliced

Burger Buns

Mayonaise

Directions:

Form the beef into patties.  In a shallow baking dish, add some of the teriyaki sauce, place the beef patties on top in a single layer, turning to coat all sides with the marinade. (Be sure to reserve some marinade for the pineapple slices). Cover container and refrigerate 4-12 hours. 

Place pineapple slices in a separate container, add enough marinade to coat well, cover dish and chill.

Preheat grill to medium heat. Cook hamburgers 3 to 5 minutes per side, or to desired doneness. When you flip the burgers, add the pineapple to the grill and cook until grill marks show, turning once.  About 1 minute before the burgers are done, place slices of cheese on top of each patty to melt.  

To assemble burgers:  Spread mayonnaise on the top and bottom of each bun.  Place hamburger patty on bottom bun and top with 1-2 tomato slices, and 1-2 grilled pineapple slices.  Cover with about 1/3 cup shredded lettuce and place top bun on sandwich.
