Boil a kettle of water. Meanwhile, pour oatmeal in a bowl. Add a little butter, brown sugar, cinnamon, and a pinch of salt.
If there's time, start a pot of coffee, and maybe do some little cleaning projects around the kitchen (I always seem to have dishes).
When water boils, pour in just enough to cover oatmeal in bowl. Set a plate on top of the bowl to keep the steam from escaping. Wait about 2 minutes.
Maybe use that time to pour yourself a cup of coffee or slice up a piece of fruit to go with breakfast. Check on oatmeal. If water is absorbed, it's ready. Pour in a little milk if you're up for it.
