What's some good meatless road food?

In August, I’m going to be driving to GenCon and I’d really prefer to bring my own snacks. Usually, the only food available in the convention center is meat, candy, or super expensive. I’d like to be able to bring my own snacks to save some money and make sure I don’t gain ten extra pounds in four days.

What I am looking for is food that is somewhat healthy, has no meat and doesn’t require refrigeration or cooking. I’ve just discovered vegan jerky which I plan on stocking up on when I go but can you help me out with other snacks? Thanks guys, I appreciate it!
