Yeah I know, offseason topic. Getting close to punting this to some place 10 pages down.
But for now...
What constitutes a sandwich? Is it strictly defined as two pieces of bread, with some kind of filling in-between? And if so, are hamburger buns considered to fulfill that definition of bread, and thus a hamburger is a sandwich?
What about the two pieces of bread specification, is that even valid? Is a sub on a roll that's split down the middle, NOT a sandwich, because it is not technically two pieces of bread?
And if a sub is considered a sandwich, when it's really more of a bread-based wrap, then are ALL wraps fair game to be called a sandwich? Is a taco a sandwich?
When I was in grade school, pretty much every day I took my sack lunch. And my friend and neighbor who was Mexican-American, also brought his sack lunch. And we'd sit down for lunch together and he'd open his lunch and bring out a refried bean and cheese taco, or a carne guisada taco, or an al pastor taco, and he always referred to them as his "sandwich."
