Founded in 1906 by Salvatore Lupo, a Sicilian immigrant, the store was one of many family owned, neighborhood grocery stores during the early 20th century, when the French Quarter was still predominantly a residential area. It is famous as the home of the New Orleans muffuletta sandwich invented by Salvatore Lupo, to feed the Sicilian truck farmers who sold their produce at the Farmer's Market on Decatur Street in the French Quarter. Central Grocery remains today in the New Orleans French Quarter. A muffuletta (muff-uh-LOT-uh) is a sandwich made with a Sicilian seeded bread commonly known as muffuletta bread. An average muffuletta averages 10 inches in diameter. The inside of the muffuletta contains ham, salami, mortadella and provolone cheese and olive salad. The meats and cheeses in the muffuletta can be found at ay local delicatessen; however, what separates most muffuletta sandwiches is the olive salad.
