Submarines, grinders, hoagies, heroes, po' boys what do you call a stuffed sandwich on a long roll? Whatever its regional name, there's nothing like a classic overstuffed sandwich starting with the perfect roll. These no-knead rolls aren't crispy and crunchy like baguettes; while they feature the baguette's open texture, they're more chewy than crusty. In addition, they're flattened off slightly on top, the better to hold a full load of filling.
