A specialty of New Orleans, this hero-style sandwich originated in 1906 at the Central Grocery, which many think still makes the best muffuletta in Louisiana. The sandwich consists of a round loaf of crusty Italian bread, split and filled with layers of sliced provolone, Genoa pimientos, celery, garlic, cocktail onions, capers, oregano, parsley, olive oil, red-wine vinegar, salt and pepper. The olive salad is what sets the muffuletta apart from any other sandwich of its ilk.
