Good for you, Howie!
I was gonna say the same thing as Jen. I airpop some popcorn before I leave & stick it in a big ziploc. No salt or butter, maybe some cayenne, garlic powder or smoked paprika to keep things interesting. If not that, then I like the little (plain!) squares of shredded wheat. That way I am getting some fiber & no one is asking, "Don't you want any ________.?"
Definitely an NSV!
