Here's an easy one, but you have to like brats.
6 beer brats
10-12 small red potatoes quartered (don't peel)
1 white onion sliced
1 large jar of Stienfelds Sauerkraut, or any other good kraut. It needs to be enough to cover the brats, taters, and onions.
1 bottle of dark beer
S&P to taste
Brown the brats in a skillet, then put into the crock pot. Cover with the onions and potatoes. Then cover that with the Sauerkraut, pour on the beer. Cover and let simmer for 1 hour or until the brats are tender and the kraut is sweet.
