Every Foodie has to make a pilgrimage to the Central Grocery in New Orleans and taste one of their muffuletta sandwiches. Legend has it that the muffuletta was created in this very spot in 1906. If you expect all New Orleans food to be French or Creole, you are wrong, the Central Grocery was an Old-World Itlalian deli and still has that vibe going today.
You might therefore think that you can make any old Italian hoagie and call it a muffuletta. No you can't. A muffuletta is always served on a round roll. It then uses authentic Italian mortadella (Italian salami) turkey, ham and cheese. In order for it to taste like it came from the Central Grocery Co., you have to use their olive tapenade spread.
