Cut the stem off the mushrooms, and stir the ingredients for the marinade together (oil, vinegar, salt, pepper, honey, soy sauce, fresh chili, and chipotle powder). I would add some finely chopped garlic to the marinade here if you don’t have a sensitive stomach like me! Soak the mushrooms in the marinade for about 20 minutes.
Meanwhile, you can prepare the sauce and the vegetables. Just cut all the vegetables thinly, and squeeze the lime juice on the avocado. Stir together mayonnaise, dijon mustard, honey, chipotle powder, salt, and pepper!
Heat up a frying pan with some olive oil.
Now fry the mushrooms for about 5 minutes on each side. When they are done, put the cheese on top and let it melt for a minute.
Assemble the burger by cutting the bun in the middle and toasting it slightly, then add the dressing on the bottom and top half. Put the lettuce, tomato and onion slices on the bottom half, add the mushroom and put the avocado slices evenly on top of the burger. ENJOY!
