If I had a photo, I would most certainly use it. That is... unless the photo I have sucks. For now, you'll just have to picture a big heaping helping of
3 buns - something good like brioche would be perfect
Directions
Put ground beef, garlic, ginger, salt, pepper and soy in a large bowl and mix to combine then shape into patties - just don’t over mix or pack patties too tight cuz they’ll be juicier if you don’t
Heat a small pan, add a tablespoon of neutral oil and cook mushrooms until softened - season with salt & pepper, keep warm and set aside
Heat grill and put on patties & pineapple slices - cook burgers until desired doneness (about 5 minutes each side) and pineapple until good grill marks appear - brushing both with teriyaki sauce once flipped
While they cook, combine mayo, a couple tablespoons teriyaki sauce and sriracha - mix well and set aside
When patties are almost done, add cheese, close lid and allow to melt and toast buns
Build burgers: bun, sauce, lettuce, patty, mushrooms, crispy onions, top bun
