This New Orleans po’boy is piled high with fried oysters.

This is the hero to beat all heroes. Invented by Salvatore Lupo, a Sicilian immigrant, in the 1930s at the Central Grocery in New Orleans, the muffuletta once served—and still does—as a hearty lunch for local workers. The key ingredient is the sandwich’s olive relish, which suffuses the bread with its herb-infused flavors. The relish may be prepared up to three days in advance and refrigerated.
