In a large bowl add the ground beef, salt, pepper, garlic powder, onion powder, ginger, soy sauce and pineapple juice. Gently mix together until well combined.

Divide the ground beef mixture into 6 equal parts for ⅓ pound burgers or 8 equal parts for ¼ pound burgers.

Gently roll each portion into a ball, then flatten it between your hands, gently shaping into a circle. Indent the center of the patty. This helps prevent it from puffing up too much in the center while cooking.

Heat the grill to 400°. Place the onion slices and pineapple slices on the grill grates. Cook for about 3 minutes to char them and get some good grill marks. Remove to a plate or to indirect heat on your grill.

Place the patties on the grill, and close the lid. For medium burgers, cook for 3 minutes, then flip the burgers, close the lid and cook for an additional 2 minutes. Place a slice of cheese on each burger and cook for 1 more minute. (see FAQ’s for additional cooking times)

Remove the burgers from the grill. Tent them with foil and let them rest for a good 5 minutes. This allows the juices to redistribute into the meat.

Build your burger. Place each burger on a bun spread with mayo, top with a grilled pineapple slice, grilled onion slice, bacon, teriyaki sauce, barbecue sauce, lettuce, and any other toppings you desire.
