New York–style pizza is a pizza made with a characteristically large hand-tossed thin crust, often sold in wide slices to go. The crust is thick and crisp only along its edge, yet soft, thin, and pliable enough beneath its toppings to be folded to eat. Traditional toppings are simply tomato sauce and shredded mozzarella cheese. This was a popular meal among poor Italian Americans due to its low cost.
