I haven't tried this yet, but hear that parched corn is a fantastic old time survival food. It supposedly keeps for a long time, is nutritious, provides fiber, and a handful can keep you going for a while. It was a favorite of the American Indians.
They are called Corn Nuts. They are a favorite of mine too, particularly the
limon picante flavor. <img src="/images/graemlins/grin.gif" alt="" />
