This is excellent. I took liberties and added ingredients. Really easy to put together.
I made this again and simply threw all the ingredients into the crockpot. Only cooked the bacon separately. Cooked for 8 hours on low and refrigerated overnight. Most excellent.

Ingredients

8 oz bacon
1lb. Smoked sausage, sliced
Diced onion
Diced celery
Diced carrot
Large head of cabbage, cored and chopped
2 lb. jar or bag sauerkraut, rinsed
6 cups chicken broth
Salt and pepper to taste

Directions

In soup pot - fry bacon slices - remove from pot and crumble
In the bacon fat (or a bit of olive oil) brown the smoked sausage.
Now add onion, celery, and carrot and sauté for a few minutes.
Add the cabbage, sauerkraut and chicken broth. Return the bacon to the pot
Mix well and ring to a boil. Lower temp to a simmer and cook about 1 hour.
Add salt and pepper if you wish.
