The usual biokiste-driven improv: lightly brown some sliced bratwurst. Add leek, diced carrot, and minced garlic and cook for a few minutes. Add chopped red cabbage and a good pinch of salt and let cook another couple minues. Add good chicken stock, some diced dried tomatoes, a bay leaf, and a bit of tomato paste and simmer until the cabbage is ready to eat. Serve over rigatoni.
