The FavSandwich(JP: ファボサンド) is an unused consumable in Chapter 1 of Deltarune. It restores 500 HP, which currently makes it the most powerful single member healing item in the game, not counting items that fully restore the HP of a party member.
(Huh? I didn't know Kris liked this flavor.)[When using it on Noelle]
Trivia
The FavSandwich could possibly be a reference to Mother 3's Omelet, which fulfills a similar purpose in being an unobtainable consumable item that heals a significantly high amount of HP, while coincidentally being the protagonist's favorite food.
