bean-based travel food

[Guest guest]

I'm looking for recipes for a bean-based travel food that I can just

stick in my pack and have some protein when other suitable foods are

scarce. I can always find calories, but protein is sometimes hard to

find. Vacuum-packed might be a possibility but no cans or

refrigeration. [Forbiddens: soy, gluten grains, oats, quinoa, amaranth,

casein, peanuts, chocolate.] I can eat tree nuts in small quantities

but don't want to rely on them. Any ideas?

 

TIA, Nancy
