Good suggestions on the Atom page, but they also resupplied often with perishable foods such as fresh fruit, vegetables, etc, and rarely made passages that lasted for more than a week or few. They even kept ice on board when they were able to. Still, the page has some good suggestions like sprouting seeds and using TVP, etc.
