1large head green cabbageabout 2 1/2 lbs, cored and cut into 1-inch pieces
1yellow onionquartered and sliced thinly
2medium size Yukon Gold potatoesabout 3/4 lb, peeled and cut into 1-inch pieces
2cupssliced smoked kielbasa or andouille sausageoptional
salt to taste
ground black pepper to taste
Heat the butter in a large cast iron pot or dutch oven over medium-high heat. Once the butter starts to shimmer, add the sliced onion and saute, frequently stirring until just soft, about 3 minutes. If using sausage, add it together with the onion. Add the rest of the ingredients, stir and bring to boil. Lower the heat to medium-low, cover and simmer until the potatoes are fork-tender, about 15 minutes, stirring occasionally.
Increase the heat to medium-high and cook uncovered until all almost all the remaining liquid in the pot has evaporated, stirring gently occasionally, about 12 minutes.
