Cabbage and Brats

Fennel (one bulb, sliced) sauteed in butter, then braised in just a little water with cabbage (half of a huge head, sliced), three small Yukon Gold potatoes (halved and sliced as thinly as you can manage), a couple carrots (sliced), and one pound of smoked Bratwurst (sliced into coins).  Quick, satisfying dinner for those nights when it is already cold and dark when one gets home from work.
