I recently ate a similar dish at a wedding in Italy, where it was cooked in a large, shallow dish. It has the same vibe as a Greek moussaka, but uses pasta rather than potatoes in the layering, making it more of a lasagne bake. The fresh sheets you can buy in supermarkets are very good and well worth using.
Pizza has long been deemed a fast food though all the ingredients that go into a pizza have the potential to be healthy. That, however, depends on how many toppings and how much cheese you like your pizza loaded with.
