The Legend of the Po’ Boy Sandwich

The Po’ Boy legend started in the 1920’s in New Orleans when streetcar workers went on strike. A local restaurant wanted to help these men out when they visited the restaurant and provide a lot of food for a small amount of money. They took French bread and stuffed it with just about anything they could find. They called the sandwich the “Poor Boy” for the men they were trying to help.

Through the years the name was shortened to “Po’ Boy” which remains a New Orleans tradition today.
