Clean the pointed cabbage and remove 8 large leaves. Quarter the remaining cabbage, cut out the stalk and cut the cabbage into strips. Blanch the cabbage leaves in plenty of boiling salted water for 1-2 minutes.
Rinse briefly under cold water, drain well and cut the leaf veins flat. Peel and finely chop the onion. Knead half of the diced onion with the mince. Place 2 cabbage leaves overlapping next to each other and put 1/4 of the minced meat mixture on one end.
Fold the sides over the filling and roll up the leaves. Stick the roulades firmly with wooden skewers. Heat the oil in a pan and fry the roulades briefly while turning. Add tomato sauce and 4-5 tablespoons of water, bring to the boil, cover and braise for 10-15 minutes.
In the meantime, put the pasta in plenty of boiling salted water and cook for about 6 minutes until it is bubbling. Pour onto a sieve, rinse briefly under cold water and drain. Heat the fat in a pot and fry the remaining onion in it.
Add the pointed cabbage strips and braise everything for about 5 minutes while stirring. Season with salt, pepper and nutmeg. Mix noodles and pointed cabbage. Arrange vegetable noodles and pointed cabbage roulades with tomato sauce on 2 plates.
Serve garnished with parsley.
