You can buy a large 25 pound bag of Whole Wheat grains and make an easy hot cereal from it that tastes great. While I do not know all the stores that carry it I know for us our local Walmarts carries it in the flour section of the store. You can also get it at health food stores ( although may be pricey) or you could try your local feed and grain store if you tell them you need clean wheat for human consumption. It costs us $14 for the 25 pound bag at Walmarts.
Take a cup of the whole wheat and you can crack it in a blender on high speed for a minute. Put in pan and cover with water. Bring to boil and turn down heat, cover and continue gently boiling for 5 minutes. Soak overnight ( wheat will suck up all water)
In morning add more water to whatever consistency you like and bring to a gentle boil again cooking for another 5 to 10 minutes.
Once done you can then add whatever you like for a tasty hot cereal such as cinnamon, molasses, raw honey, bananas or whatever items you like! Delicious!
