Do I have to hydrate soy beef granules? If so, how?

Morningstar Farms makes several ground beef-like meat substitutes: Burger Style Recipe Crumbles and Ground Meatless. Both are precooked and ready to use, making them convenient and healthful alternatives to meat in almost any recipe where you'd normally use ground beef. They do not have to be hydrated, and they are low in fat and fortified with iron and vitamins, including B-12, which can only be obtained from animal products and supplements."
