What to Eat in Italy

True pizza Napoletana (it's a TSG-protected food) comes in one of three varieties: pizza marinara, which is topped with tomato, garlic, oregano, and extra virgin olive oil; pizza margherita, a tomato, sliced mozzarella, basil, and extra virgin olive oil pie; and pizza margherita extra, which is topped with fillets of an extra-special variety of mozzarella from Campania. Given the opportunity, we'd dig into a slice of each, though we're slightly partial to the margherita varieties.
