Remove 3 outer leaves of romaine for sails; set aside. Chop remaining romaine; toss with dressing. Cut bread into 20 slices, leaving slices attached at the bottom. Between every other slice of bread, layer the cheese, turkey, ham, salami and romaine mixture.
Poke two holes in each reserved lettuce leaf, one about two inches from the top and one about two inches from the bottom. Place a pretzel rod through both holes on each lettuce leaf forming a sail. Place sails in the sandwich.
To serve, cut completely through the bread between the plain slices.
