Cabbage: Yes, you will eat it. And you will like it. Canned, frozen, or pressure-cooked, most of the food a sailor eats on a passage has the texture of geriatric oatmeal. Cabbage, on the other hand, keeps forever, is full of vitamins, and can be sliced thinly, then made extra-crunchy with a fresh water bath. You can even toss it with this gutsy ginger dressing and pretend it's delicious.
