I found this recipe in a Weber BBQ cookbook and liked it for it's simplicity and for the fact that I could let them cook away on the grill with a minimum of supervision. My guests loved them! The next day, I re-grilled the leftovers and they were just as good, if not better, than they were the night before. My brats were quite large with 4 of them to a pound so the serving size here is approximate.
Set up your grill for cooking indirectly over medium heat- for a gas grill just leave one burner unlit and for charcoal, move hot coals to the outside edges of the grill.

Place a foil pan in the center of the cooking grate and pour the beer into the pan, then add onion and green pepper; place brats on grill alongside the pan and cook, turning occasionally, until they're lightly browned.

Place brats into the pan with the beer and vegetables, cover grill and cook for 25 minutes.

Serve on buns with mustard and chopped onions.

Leftover brats can be re-grilled right on the grill for several minutes, until hot.
