That dictionary on your Mac says a sandwich is "an item of food consisting of two pieces of bread with meat, cheese, or other filling between them, eaten as a light meal." Ever the iconoclasts though, Louisvillians have destroyed that definition like a horse with two broken legs at the track. One of Louisville's nine most iconic sandwiches uses just one slice of bread, another doesn't use bread at all. And there's nothing light about any of them.
