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
Lets make the teriyaki sauce first: put one cup of water in a small pot and add brown sugar, soy, honey, ginger & garlic - stir well to mix and bring to a simmer
Mix remaining 1/4 cup water with cornstarch well, then stir into simmering sauce
Stir well and it’ll thicken over a couple minutes, set aside until ready to use - btw it’ll keep a week or so in your fridge
Combine ground beef, diced green onion, soy and salt & pepper in a large bowl - mix to combine and shape into 3 patties
Clean & heat grill to medium high - use cooking spray
Put on pineapple slices and patties - and cook pineapple until well marked on both sides
Cook patties on the first side and when you flip, start basting with the teriyaki sauce - cook until both sides are done to your liking - saucing as you go
Grill buns, and build burger - bottom bun, mayo (maybe add a little more sauce to the mayo first), patty, pineapple, lid
