Step 1
Place the cabbage, butter, and mushrooms into a large pot or Dutch oven with lid. Season with seasoned salt, and pour in the beer. Bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer. While the cabbage is simmering, combine the kielbasa, garlic, onion, Worcestershire sauce, and balsamic vinegar in a skillet. Bring to a simmer over medium-high heat, and cook until the onions have turned translucent, about 5 minutes. Stir the sausage mixture into the cabbage mixture, recover, and continue simmering until the cabbage is tender, about 15 to 20 minutes more.
