A muffuletta is a round loaf of italian bread filled with italian meats and provalone cheese and a special olive salad. The olive salad is essentially a combination of chopped olives and marinated veggies (celery, carrots, etc.) so it's got some of the briney taste from the olives but is also vinegary. I hate olives but I can handle them on this sandwich. The photo above is of a sandwich made by Central Grocery in New Orleans, the creator of the sandwich. Yum!
