My on-the-road survival food is to buy a can of cooked beans...chickpeas, navy, lentils. Then, stop at a farmers stand, grocery store, etc. and pick up whatever veggies look good...a pepper, carrots, some odd veggie that looks edible raw. Toss it all together with some oil and vingegar and voila', a heathy, high protien salad. Tasty, too.

It is a good way to make do with the local farmer's market. We do this regularly when we travel--one day is always to try to find some local veggies and make a salad. Some are just edible, others have been quite tasty.
