I keep peanut butter packets, Tanka bars, Almonds, those nasty bright orange cheese crackers (a weird thing that I just happen to like) & hard candies. I do eat them regularly as well so they're not "long term." They're often my lunch or breakfast if I'm running late or just feeling hungry. Of course, then I replace them.
Definitely recommend the Tanka Bars, especially the spicy ones!
