I Looooove fried sauerkraut on beer brats. A friend of mine turned me on to it. It's a stick of butter, then half a sweet onion, peppers of your choice (I had to go with serranos or the missus wouldn't eat it) then a large can or bag of sauerkraut (drained). I just keep stirring it around on medium low until it absorbs all the butter and begins to brown a little. Yum!
