What food would you seek out in the Zombie Apocalypse?

In the hilarious movie "Zombieland" Woody Harrelson's character's focus is on tracking down a Twinkie. It's no easy task given that most grocery stores resemble ghost towns, filled only with the living dead. What one food item would you hunt down in the Zombie Apocalypse? While I doubt I'd be as focused as Woody, I'm willing to bet "Hello Panda" cookies would hold up well in such an environment.
