Clean, wash and cut the leek into strips. Peel and finely dice the shallot. Wash veal cutlets, dab dry and season with salt and pepper. Cover with two sage leaves and a slice of Parma ham, fold over and pin with wooden skewers. Cook the pasta in boiling salted water for ten minutes.
In the meantime, heat oil in a pan and fry the escalopes for two to three minutes on each side. Remove and keep warm. Sauté the shallot in the frying fat. Deglaze with wine and reduce by half. Add butter cubes bit by bit. Season to taste with lemon juice, salt, pepper and sugar. Add leek one minute before the end of the pasta cooking time. Drain the leek noodles and let them drain. Arrange on plates with Saltimbocca and sauce.
