The typical Greek version has a bottom layer that is bucatini or other tubular pasta, with cheese and egg as a binder; a middle layer of ground beef, veal or lamb with tomato and cinnamon, nutmeg or allspice; another layer of pasta; and a top layer of sauce, varying from an egg-based custard to a flour-based Béchamel or a Béchamel with cheese (known as Mornay sauce in France). Grated cheese is often sprinkled on top. Pastitsio is a common dish, and is often served as a main course, with a salad.
