Lasagne is an ancient food. The Romans were dishing it out during the heyday of the Roman Empire. A 14th-century cooking manuscript directs the cook to boil the lasagne noodles (made without eggs) in capon broth and then layer the noodles with grated cheese. In my version, freshly made noodles are layered with thin, lengthwise slices of eggplant and topped with tomato sauce.
