Impossible. The US military has been trying for literally decades to make a decent pepperoni pizza for their MRE kits and have only recently managed to make something that is good enough that it can be said that it vaguely resembles the shitty institutional pizza that they served for lunch when you were in school.

You just need a can 14" round and 2" tall or whatever the dimensions of the pizza.
