I'm just a big fan of the Quick 1-minute Quaker Oats 1/2 cup + 3/4 cup Skim Plus milk on the stove. I like to just heat the milk up quickly - as soon as its about to foam over the top of the pot, dump the oats in and cook it for a minute. When its done and I put it in a bowl, I just cover the top of the oatmeal with honey.

As for the cleanup - when I'm done eating, enough time should have passed for the pot to cool. I put the pot, spoon, and bowl into the sink and soak it in soapy water until I come home from work. By the time it soaks - everything comes off instantly!
