Here's a trick that I've done in the past: buy a Presto popcorn popper. You can then buy organic grains in bulk--wheat, barley, rye, even oat groats--and pop/parch them in the popper. You get the nutty flavor and bioavailability of breakfast cereal, but no secret additives and a guaranteed clean breakfast. If you prefer hot cereal, you can then mill (or grind) the roasted grains to make instant porridge--just add boiling water and stir. (You can also do the same with lentils and split peas, mix in dried seasonings, and have instant soup mix). All of the convenience, none of the packaging, none of the poison.
