A "Sandwich" is a food item made by putting an edible object, most commonly cheese or ham, in between two slices of bread. It comes in a variety of flavors.
Consumption in the series
Wander brought a pair of sandwiches, one with mayonaisse and one with mustard, to his picnic, unaware that Lord Hater and Emperor Awesome were fighting for the prize of getting a wish. He handed the mustard sandwich to the destroyed robot of Hater, and one of the watchdogs enjoyed it.
Some sandwiches were also served during the titular event in "The Fancy Party".
The only pieces of a sandwich that remain constant in almost every variation are a pair of slices of bread. In between the pieces, anything that is edible can be added, like mustard or mayonaisse.
