It's not a real recipe, but I like to share things that taste ridiculously good.
Basically, I bought huge mushrooms, fried them in a little margarine on medium heat and with a lid from both sides, until they were relatively soft. Then I deglazed with some balsamic vinegar and added a little thyme. I toasted a burger bun and put some "like creamcheese" on it. Plus tomatoes and salad. Done.
