What are some good recipes that you can store outside of the refrigerator for a day?

This weekend I’ll be participating in a running relay race, and to keep the costs from running amok, we intend to make our dinner for Saturday evening on Friday. This means that we do not have access to a refrigerator to keep the food edible for a day. We were planning on making a pasta salad, but it isn’t ideal (you need to preserve the pasta). I have a few ice packs, but that’s about it.

What are some better (easy and preferably cheap) recipes that you can make a day ahead and bring along? Some of the participants are vegetarians, so bonus points if the recipe is too.
