The difference between deep-dish pizza and most other styles is in the crust.

Because new immigrants didn't have a lot of money, they relied on cheap venues and cheap food for weddings, known as "peanut weddings." To stretch the amount of beef served at weddings, someone came up with the idea to slice it thinner to serve more people, and thus Italian beef was born. The thinner cut became hugely popular and eventually came to be what is now known as Italian beef today.A traditional Italian beef sandwich is made of thin slices of roast beef seasoned with dry herbs and spices and bathed in broth and cooking juices, otherwise known as au jus.
