Beer-Braised Brats

Using a toothpick, pierce casing on each brat several times.

Place brats, onions, ground mustard and pepper in a large, grill-proof pot.  Slowly pour in beer.  Stir to combine.

Place pot on the grill.  Simmer for 25 minutes or until brats are cooked through.

Remove brats from the pot.  Briefly place on the grill to crisp the skin.  Lightly grill the buns if desired.

If desired, remove onions from pot and place in a disposable foil pan.  Add butter and place pan on grill.  Cook onions until golden brown, about 5 minutes.  

Place brats in toasted buns.  If desired, slather with stone-ground mustard and top with grilled onions.
