A traditional-style muffuletta sandwich consists of a muffuletta loaf split horizontally and covered with layers of marinated olive salad, cheese (mozarella and/or provolone) and charcuterie (salami, ham, porchetta, anything really).
The signature olive salad consists of olives, roasted red peppers, hot pepperoncini, diced with the celery, cauliflower and carrot found in a jar of giardiniera, seasoned with oregano, covered in olive oil, and allowed to combine for at least 24 hours.
THe breat is described as being somewhat similar to focaccia, but different in that it is a very light bread, the outside is crispy, and the inside is soft. At a pinch, any good crusty bread will do!
