10. Hardtack

Used as a highly portable biscuit for sea voyages and military campaigns for centuries, hardtack is simply baked and baked and baked until there is virtually no moisture left. This allows it to keep for months without refrigeration, but also makes it hard as a rock and dry as a desert. It had to be dunked in liquid to render it edible, but once choked down it would provide you with plenty of dietary fiber and carbs for quick energy if made with a healthful flour.
