Mix all the grains and brans and store in jar. You can use teff, sorghum, various varieties of millets, buckwheat, kasha, amaranth, wheat and oat bran as well.
When ready to cook, take one quarter cup mixed whole grain per person, add 2 whole cardamons (optional, for taste) and cook with 1 cup water for about 10 minutes, stirring once in a while to make sure the cereal doesn't get stuck to the bottom of the vessel. Remember that cardamoms are only added for flavor- discard them after cooking so you don't chew them by accident.
