Cook the pasta in salted water until al dente, then drain and drain.
Heat the butter in a pan, add the breadcrumbs and fry briefly until light brown. Add the pasta and sugar, mix everything well and reduce the heat. Beat in the egg and stir everything quickly. When the egg is set, serve hot immediately.
If you like, you can also serve cinnamon sugar or compote at the table.
Can also be prepared well with pasta from the day before.
