The Poor Boy Sandwich (also known as the Poor Man's Sandwich, the Poor Man's Po'Boy, or the Poor Man's Sub) is said to have originated in Louisiana during the Great Depression, when people would cut a French baguette into halves and fill it with meat or other ingredients that were affordable, such as potatoes, shrimp, and oysters. The name Poor Boy refers to people who had limited financial means, so the sandwich was a way to get a filling meal without spending a lot of money.
