Ewww--I don't think I'd care to hard cook my eggs in my oatmeal. You end up with what cooks off of the shell in the cereal.

I do oatmeal overnight in a small 1 quart crock pot (slow cooker) regularly. It works as long as I start with boiling water. I use it with soy milk, but if you want to add more protein you could cook it with milk instead of water. Powdered milk is what I've used. It doesn't add much flavor.
