When my brother and sister and I would eat leftover pizza for lunch, we would sometimes pretend that it was space rations, or space pizza. (There were often elaborate play sessions centered around pretending that our ranch house was a two-story space ship. The kitchen was the galley.)
I have even made pizza play a role on the spacefaring menu in most of the worlds I’ve created. It just fits that a food as ubiquitous as pizza would become a staple of a space-faring civilization.
Well, how about 3D-printed space pizza?
