Many recipes call for several kinds of cheese, most often ricotta, mozzarella and parmesan.
A variant is Lasagne verdi (green lasagne) which is the normal egg pasta with spinach added.
Lasagne was first recorded in the 13th century when it was used in a layered dish. This was not modern lasagne as tomatoes had not yet been discovered by Europeans.
Lasagne is the favorite dish of the fictional cat Garfield.
