Kielbasa, Cabbage, and Potato Boil

Developed September, 2020. Fast, easy, and cheap supper.

1 lb kielbasa or similar sausage
1 T vegetable oil
4 c green cabbage, cut into wedges
1-1/2 lb thin-skinned potatoes cut into 3/4 inch pieces
2 T beef stock concentrate (Better Than Bouillon™ is good)
6 peppercorns
water to cover 

Cut the sausage into four pieces crosswise and then each piece in half lengthwise to yield 8 pieces. Heat the oil over medium in a large saucepan.  Fry the sausage, cut face down until browned and crispy. Add the cabbage and the seasonings, cover with water and bring to a gentle boil.  Cook 10 minutes, add the potatoes (and onions if using), and continue cooking until the potatoes are tender, about 15 minutes. Adjust seasoning. Serve in a bowl with some of the stock. Offer spicy mustard on the side. Variation: Add a medium yellow onion quartered through the root with the potatoes. Serves four.
