1To assemble, cover cut sides of bread with a generous amount of the dressing. Starting with flat side of bread, place a layer of arugula, ham, hard salami, Mortadella, Provolone, Capicola, Sopressata, Asiago, and Genoa salami. If you have left over meat and cheese, add it. End with sliced tomato. Top with the other bread half.
2Wrap with plastic wrap and refrigerate for at least 2 hours. Allow to come to room temperature before serving. Serves 4-6.
