Well, I don't know, but it sure was tasty!
I went into this meal on Thursday night thinking "I am attempting to use up some sauerkraut I made forever ago, so if it fails, it was food I already wasn't eating."
2 cups of that and chopped it up.
1/2 a large onion, chopped
a bit of red and green pepper I had chillin' in my fridge
a large can of tomato sauce
1/4 of a Polska Kielbasa sausage, chopped (not "coined") (a little more than 1/2 a cup)
I made this in a 5x9 bread pan
Mix all of that together and add a bit of vinegar, brown sugar, plain yellow mustard, Worcestershire sauce, and we'll see what we have when it's done!
I cubed some bread I had in the fridge and coated it with melted butter and put it on top when it was already well heated through and cooked it about 15 minutes longer.
It was delicious! Next time I might serve it over pasta. I also liked the kielbasa in this a lot because even though I didn't add very much, it is a strongly flavored meat so you could definitely still taste it.
