On low heat, add sliced onion rounds and cook on each side for 7 minutes (no oil needed)
Set onions aside .
In the same pan, place your burger patty in there on medium-low heat with the lid on the pan to help cook the burger evenly.
While the burger is cooking, place two pieces of lettuce on each bun.
On top of the lettuce add your vegan mayonnaise and bbq sauce (tip: if you’re using bagels, it helps to put the mayonnaise and bbq sauce on the lettuce rather than the bagel to keep the burger less messy to eat).
By now the burger should be ready to flip.
Once you flip the burger, add vegan cheese and put the lid of the pan to help circulate the heat which will help melt the cheese.
After about 5 minutes, or however long it takes to nicely cook your vegan burger, add the patty to one of the buns
Layer on your lightly grilled onion rounds and lots of mushroom jerky.
Put everything together and enjoy!
