Right, so, this post is going viral on Tumblr today.
So, I checked and — at that very moment — according to Wikipedia, "sealed crustless sandwiches," A.K.A. Uncrustables, could be categorized as a type of ravioli.
According to the entry, they "weakly fit categorisation criteria for burritos, dumplings, and ravioli, as well as being described as a sandwich by name." There was also a very upsetting tidbit about cereal, which is a whole different debate entirely.
However, in the time it took me to draft up this post, the Wikipedia entry was edited to re-categorize sealed crustless sandwiches as primarily a sandwich (debated.)
So, let's settle this: are Uncrustables a type of ravioli, sandwich, or something else entirely? Tell us what you think in the comments!
P.S. For what it's worth, Uncrustables weighed in on Twitter and clearly states that their product is a sandwich!
