It’s a simple recipe: bread, filling, bread. But sandwiches had to get their scrumptious start somewhere. Joy Dolo and co-host Ben travel back to a time when putting food between two slices of bread was a culinary revolution. Reporter Tracy Mumford introduces us to two innovators duking it out for the credit, and Brains On host Molly Bloom treats us to some strange historical sandwiches, including a sandwich loaf.
