Why do Italian people eat risotto?

Lasagne tastes good, is filling, is very nutritious, the ingredients (except for meats) are easily stored, many even without refrigeration, like dried pasta. It can be made with freshly made pasta as well. Part of the ingredients, like the sauce, can be made well in advance and canned or frozen for longer term storage. It is inexpensive to make and contents are easily obtained by ordinary people. It can be varied so it isn't boring as: with meat, without meat, with spinach as a vegetarian dish, with meatballs, with different cheeses, with onion, with mushrooms, with different herbs, etc. American people love lasagna, too! Although the most popular lasagne in the U.S. is the baked version, it can also be eaten without layering and baking for a quicker meal. You might think of it as the Italian version of a casserole.
