Place brats in a saucepan with the onions and butter, cover with beer. Bring to a boil and reduce to simmer until brats are cooked. Remove brats and set aside beer mixture. Grill brats in hot grill pan until golden brown and return to beer mixture until ready to serve. Slice and serve on top of cabbage.
