Flatbread vs. Pizza — What's the Difference?

A flatbread is a bread made with flour; water, milk, yogurt, or other liquid; and salt, and then thoroughly rolled into flattened dough. Many flatbreads are unleavened, although some are leavened, such as pizza and pita bread.

Pizza (Italian: [ˈpittsa], Neapolitan: [ˈpittsə]) is an Italian dish consisting of a usually round, flattened base of leavened wheat-based dough topped with tomatoes, cheese, and often various other ingredients (such as anchovies, mushrooms, onions, olives, pineapple, meat, etc.), which is then baked at a high temperature, traditionally in a wood-fired oven. A small pizza is sometimes called a pizzetta.
