Cut tofu into 1/4 thick slabs. Carefully place in a plastic bag and pour soy sauce and water over it.
Close bag and place in a bowl in the refrigerator. Allow to marinate several hours or overnight, turning occaisionally.
Mix dry ingredients together and place on a shallow plate. Carefully coat the marinated tofu cubes in the mixture.
Lightly spray a cookie sheet with cooking spray and place the coated cubes on the tray.
Bake in a 400° F oven for 30-45 minutes, or until lightly browned (cook longer if you want the nuggets to have more of a dense texture, less if you like the light cheesy texture of the silken tofu).Servings: 2-4
