• Oil
• ¼ yellow onion, sliced

Directions

1. Heat cooking surface, and add a little oil in 2 spots – put the mushrooms on one, and the onions the other.
2. Cook both until nicely softened and beginning to caramelize, then add the soy to the mushrooms, and vermouth to the onions – mix then set aside.
3. Combine bbq sauce, Kewpie & sriracha, mix and set aside.
4. Heat your surface, add some more oil and the two patties, season with salt & pepper, cook until done on one side, then flip and add a slice of cheese to each.
5. Cook the egg (keeping the yolk runny if you’re cool with it).
6. When the patties are done, you can build: bottom bun, bbq sauce mix, mushrooms, patty with cheese, bbq sauce mix, 2nd patty with cheese, bacon, onions, egg, top bun with bbq sauce mix.
