Combine 1/3 cup each: (use whole grains)

Brown rice
Millet
Rye
Oats
Wheat
Flax

Mix thoroughly in crock pot. Add 4 3/4 cups water and cook on low overnight (8-12 hours)

You can buy whole grains at most health food stores. This cereal is tasty and very inexpensive to make. Leftovers heat nicely in the microwave.
