Cheerios are oats.

You can also make your own muesli. We used to do it by putting a bunch of rolled oats, dried fruit, chopped nuts, and powdered milk in a jar. Shake it all up. B'fast was a scoop of that in a bowl with cold milk poured on it. (just like store-bought cereal)

I can't eat oats anymore cuz of my damm celiac disease, so I'm left with the Metamucil. I'd rather eat muesli!
