So, I am not a fan of art that is avant-garde for its own sake. This article seems to embrace that tradition...

I mean, hooray for trying new things, but I'm so tired of the "well, what exactly IS art? THIS could be art, so I'm going to MAKE it be art" argument. Especially when used on sandwiches. Why not just be happy with creating a food without having to argue that THIS IS a sandwich?
Well, I don't know if stromboli is a sandwich, since it's more like a calzone - pizza dough rolled over ingredients. Southwestern-style sushi? That seems like a neat idea, but how is sushi a sandwich?
I don't care if you can argue it is - it doesn't NEED to be a sandwich, and in fact should not be lumped in with the sandwich category, to be considered acceptable food.
