"on the go" snacks?

hello. I am fairly new to raw. I’ve been high raw for a little over a month and really enjoying it. But I am moving back to college in two weeks and things are going to get really busy. I got a dehydrator today (yay!) and I’m wondering if there are any things that I can make now to save for when school starts and I need a snack on the run. I plan on making some flax crackers and I’m pretty sure that they won’t go bad but I’m not really sure about how long other things will last. Thanks for the help! You all are awesome!
