Mufalleta sandwiches are one of the many Louisiana takes on (subs, hoagies, etc) sandwiches. You buy a round loaf of bread (boule in some places). Split it horizontally. Then you make a relish of different olives, peppers, onions, garlic, olive oil. You pull some of the bread from the insides of the loaf and mix it into the olilve relish. Then you start layering on the bottom half of the bread. I used mortadella, hard salami, ham, a locally made cheese called Apple Jack, a sprinkle of cheddar and of pecorino romano. I sprinkled a bit of olive oil on the bread. Then you pile the olive relish so that it fills he hollow you made in the loaf of bread. Cut into wedges. Voila. If you ever are in New Orleans, have it at Napolean House. The meat and cheese can be done to whatever your taste is, and that of your guests.
