Similar to a hoagie or hero sandwich that contains an array of ingredients, the Muffuletta is most often stacked with Italian meats and cheeses that are traditionally garnished with an olive mix. Orginating in New Orleans, the Muffuletta is made in many variations using different breads and ingredients, however, the basic Muffuletta is typically made with a round loaf of Italian, French or sourdough sandwich bread, similar to a large, oversized bun. The bread is sliced in half for layers of meats and cheeses to be added. Generally, the meats may include Genoa salami, ham and mortadella. Cheeses such as provolone, mozzarella and Swiss are then layered into the meats. When the meats and cheeses have been arranged for the Muffuletta, an olive mixture is spread over the top and/or the bottom of the bread. This mixture, known as "olive salad," consists of green olives, garlic, onions, pimientos, capers, oregano, parsley, salt, and pepper that have been mixed with olive oil and red-wine vinegar. Olive mixtures similar to a homemade recipe are available in food stores that may be packaged as Olive Bruschetta Toppings. A Muffuletta sandwich may also be spelled as Muffaletta.
