Bring beer to a simmer in a pan with 1 of the onions, the mustard, and ketchup. Add bratwurst and simmer about 20 minutes. Have your grill or broiler hot. Drain the bratwurst. Grill brats and remaining onion slices about 5 minutes on each side. Grill the split rolls quickly. Fork a pair of wurst onto each and top with onions. Serve with plenty of extra mustard and ketchup and beer.
