I am going on a road trip that will be aprox. 24 hours long. I hate doing these sometimes because I usually have to eat potato chips and trail mix. This time I want to make a couple of things to take with me that are real foods and don't need to be refrigerated. I was thinking of making up a batch of hummus and bringing some veggies along, and also some cookie bars. Do you guys know of any simple things that I can make that don't need to be kept cool and won't get yucky over the course of a day? I am thinking along the lines of veggie dips and bars. beyond that, i'm stuck. any ideas? bonus points if it's healthy! thanks!
