Dehydrated pizzas were pizzas, processed to the size of a cookie until rehydrated. Once hydration was performed (in a Black & Decker Hydrator that became available sometime before the year 2015), the product would, in a matter of seconds, come out the full size of a conventional pizza.

A dehydrated pizza that measured four inches in diameter was considered quite large.

Pizza Hut sold dehydrated pizzas, which bore on the wrapper the instruction "REMOVE FROM FOIL REHYDRATE FOR 2 SECONDS". One of these had split toppings of half pepperoni half green pepper, and the McFly family consumed such a pizza for dinner on October 21, 2015.

A comment by Marty McFly Jr. suggests that a person could simply eat a dehydrated pizza without first putting it through the rehydration process. However, according to a warning on the Pizza Hut wrapper, "DO NOT CONSUME UNLESS FULLY REHYDRATED", it was dangerous to consume a dehydrated pizza unless it was fully hydrated, otherwise resulting in complete rehydration within the stomach. Marty Sr.'s response to this ("Don't be a smartass!") leaves open the question of whether Marty Jr. was joking, or was simply being rude.
