Boil potatoes as jacket potatoes, peel and cut into slices or cubes. Cook the pasta in plenty of salted water until al dente. Peel the onion and cut into small cubes. Also cut the sausage into cubes.
Fry the potatoes together with the onions in butter oil (a little oil and a little butter). Add the sausage and fry briefly. Add the noodles and fry them too until they have also got some color. Salt. Beat the eggs over the top, add salt and mix everything well.
You can prepare the dish without any sausage or without any sausage and eggs. The interesting thing is the mix of potatoes and pasta.
