Thread the uncooked spaghetti through the sausage slices (I used 5 uncooked spaghetti for each slices).
Bring a large pot of salted water to a boil. Carefully place all the sausages threaded with spaghetti in the boiling water. Cook uncovered, over high heat until al dente, cooked through but still a bit firm. Drain in a colander (be nice with them!).
Serve the Halloween worms with any kind of sauce you like.
