2 lbs. 80% or 85% lean ground beef or ground chuck
4 pineapple rings
1 Tbsp olive oil
4 slices Swiss cheese
4 romaine lettuce leaves
8 slices red onion
4 hamburger buns
Instructions
Preheat grill to medium heat.
In a small saucepan over medium heat, combine soy sauce, vinegar, sriracha, sugar, ginger, and 1 tsp garlic. Bring to a boil.
Meanwhile, in a small bowl, combine water and cornstarch. Add to the boiling soy sauce mixture and stir constantly, until thickened. Reduce heat to low or remove from heat until your burgers are done.
In a large bowl combine ground beef and remaining 2 tsp garlic (I just use my hands). Divide into 4 equal sections.
Roll each into a ball and lightly pat down the sides and middle with a fork.
Brush each side of each pineapple ring lightly with olive oil.
Grill hamburgers for about 5 minutes. Turn and cook an additional 4 minutes or to desired doneness. (Use this finger test from Simple Recipes to test for doneness).
During last 4 minutes of grilling, add pineapple rings. Grill 2-3 minutes per side and then flip, cooking for 2-3 minutes on the other side.
During last 2 minutes of cooking burgers, top each patty with a cheese slice. Remove burgers and pineapple from grill.
On each hamburger bun, lay a piece of lettuce. Follow with a burger and 2 slices of the red onion, then a pineapple slice. Drizzle teriyaki sauce generously over each one. Then dig in and indulge in the juicy deliciousness!
