I used to eat oatmeal in the mornings. Even bought special organic oatmeal from the health food stores. But oatmeal has a lot of fiber and not much more. So try flaxseed because it has Omega 3 and oatmeal does not. Flaxseed has the fiber plus other stuff. So to me its better.
I grind the seeds in one of those small coffee grinders and put it in with my morning smoothie consisting of bananas, oranges, an antioxident like acai or pure pomegranate juice. So there's no cooking. Keep it simple.
