"I don't care if you don't want to be the burnt toast, just roll the dice!"

-Mung Daal, "The Cinnamini Monster"

Toast didn't ever appear as food, but it appeared as a game piece in the episode "The Cinnamini Monster". Mung Daal, Chowder, and Shnitzel needed to win the Cinnamini Monster at a board game, and Snitzel used the burnt toast. Toast is one of the real world foods that appears in Marzipan City.
