A pizza is in the shape of a pie, but it could be said it's an open faced sandwich as well. Either way, women on this site don't know a lot about sandwiches. Which is why poor Emily had to seek our counsel!
Man... now I want pizza for dinner again! Sigh.
Aimee,
There are clearly some holes in your sandwich doctrine.
A pizza isn't just round like a pie.
It has all the other features of a pie as well, and it is even cooked in an oven.
A pizza has no pre-made bread like a sandwich...
the "bread" of the pizza, much like a pie, is only dough until all ingredients are cooked together.
I am truly saddened by your lack of understanding of the sandwich,
which has become, by virtue of it's humble perfection,
the undergirding of all Western civilization.
