Here's a Bratwurst beer-can burger on one from a month or so back:
There's no way I can in good conscience call this a burger, but God damn I want to eat one of them, though, whatever it is. That looks fantastic.
Are you familiar with the beer-can burger concept?
Usually ground beef formed into a ball, then a beer can smashed into it to create a bowl for filling, wrapped with bacon. My basic one is crumbled-cooked bacon and caramelized onions. Smoke at 300 for about an hour, top with cheddar for the last 15 minutes.
For the one pictured above, I took the basic concept of cooking brats in a beer-butter bath and turned it inside out; Bratwurst meat taken out of the casing to form the burger bowl, and filled with kraut, bell peppers, and onions that were cooked in beer and butter. Topped with a cheddar-beer sauce.
