Poor boy sandwich

"The poor boy sandwich is one of the essential flavors of New Orleans, and the roast beef is the king of the poor boys. The sandwich was invented in the mid-1920s, during a streetcar strike. Bennie and Clovis Martin, the owners of a busy restaurant on the corner of Touro and St Claude, helped the "poor boys" on the picket lines by making sandwich, on French bread, of roast beef gravy and all the little bits of beef that came with it... (not po-boy, although that has become the more common spelling in New Orleans). "
