Umberto an Italian restaurant and pizzeria in the Long Island are known for their signature dish the Grandma Pie. It is a family owned restaurant and was established in 1965 by Umberto Coreo. Grandma pie was initially prepared in-house by the homesick emigrated Italian Americans.  But in no time it became famous and Umberto was the first one to sell it commercially. It is a rectangular/square pizza cooked in an olive oil-coated pan, covered with a layer of mozzarella and in uncooked canned or fresh tomatoes. The cheese goes directly on the dough with the sauce on top. It is tossed in the oven immediately after being stretched on the pan, giving it a slightly denser and crispier crust.
