I love that EVERY TIME someone tried to defend mushrooms to me, it has ALWAYS been them arguing how good they are when you add a fuckton of other ingredients next to them. When was the last time you've heard of someone eating empty mushrooms, with no seasoning, with no side-dish (or main dish, cause mushrooms are usually the side-dish), no nothing?
I'll tell you what, a steak works pretty damn well all by itself. Even most vegetables work well by themselves.
