I prefer bratwurst simmered in beer then slapped on a hot grill for a quick finish. Mustard and sauteed onions on top with a fresh bun. They are so juicy you need a bib and safety glasses.
Wow. When I was deployed it seemed like every other day some section or detachment had a cookout with grilled brats. Could have lived on them but since Air Force was the majority we had absolutely the best messhall chow I have ever known.
With bratwurst the hotter the mustard the better.
