What a funny example of the difference between education and intelligence.
A sandwich is a piece of meat between two pieces of bread. I guess one could argue whether or not a hot dog roll is one or two pieces of bread, but I prefer my hot dog on a tortilla rolled up with the slice of cheese a dab of mayo, and just a hint of yellow mustard. Whether or not it is a sandwich is up for discussion but based on the definition, I would have to say that my version of a hot dog is a wurst burrito.
