I’ve been eating a lot of burgers lately. When I want to do something different than the classis burger with American cheese, lettuce, tomato, and red onion, I often go in the direction of a mushroom, bacon, and Swiss burger.

This recipe includes a quick and tangy homemade vinegar-heavy BBQ sauce to go on top of the burger.

Burgers with Sauteed Mushrooms, Swiss Cheese, Caramelized Onions, and Crispy Bacon

I’ve been eating a lot of burgers lately. When I want to do something different than the classis burger with American cheese, lettuce, tomato, and red onion, I often go in the direction of a mushroom, bacon, and Swiss burger.
This recipe includes a quick and tangy homemade vinegar-heavy BBQ sauce to go on top of the burger.
