Boil the pasta in salted water and drain in a sieve. Cut the sausages into pieces (I cut each sausage twice). Peel the onions and carrots and cut into small cubes.
Fry the Nuremberg sausages in a little fat on all sides in a large pan. Add the onions and let them take some color. Add the carrots and fry a little too.
Deglaze with the broth and simmer for about five minutes. Season well with salt and pepper. Stir in the creme fraîche. Now don`t let it boil anymore.
Finally add the pasta and let it warm up. If necessary, season again.
