There are a lot of rules about eating in Italy. Meal times in Rome happen at specific times with very little wiggle room and, as a general rule, Italians do not snack in between meals or eat on the run. There are exceptions, and pizza al taglio is one of them—especially if it comes from this bakery behind the flower sellers in the Campo de' Fiori. Long strips of pizza bianca get topped with slicks of tomato sauce or thinly sliced potatoes, or get stuffed with mortadella or zucchini flowers. Take it all to go and eat it while leaning against a fountain in view of a palace that Michelangelo designed.
