The NY Times has entered into an interesting discussion on what constitutes a sandwich, creating five groups for the purposes of categorizing the genre, and explicitly excluding certain items such as hamburgers, hot dogs, tacos, burritos, gyros/shwarma.
Quoting from the article
"There are sandwiches made on Kaiser or "hard" rolls.
There are sandwiches made on soft buns.
There are sandwiches made on long hero or sub rolls.
There are sandwiches made on sliced bread.
And there are what we call "singulars," which are those creations on bread that falls outside these other groups but are still vital to the sandwich landscape, like the muffuletta."
What other categories or sub categories should they add.
I also disagree with their statement that a muffuletta falls outside their five groupings... it really is just a variation on the sub/hero/wedge/hoagie.
