The burgers also should be plump things, not McFrisbees. If you can eat them without needing a shower/bath after, you could've done a better job.

I like cheese on them sometimes, as well as other things although I prefer mayo to ketchup, mustard or Miracle Whip. But if one is slurping up a masterpiece, the taste of the meat (+onion, +shrooms +salt & pepper) should be enough to rapturize your ass.

I've never had pickled walnuts, but the idea sounds great.

Friends like using a toasted English muffin instead of bun or bread. Tastes great, but can sog faster.
