Fry the meatballs for about 10 minutes while turning. Put aside. Melt the fat in the frying fat. Fry the remaining onion cubes in it until golden brown. Add the savoy cabbage and toss in. Season with salt and pepper. Stir in crème fraiche. Wash the parsley and chop it except for something to garnish.
