Pour, Sleep, Eat.

It is that easy. You just add enough milk to cover the oats the night before and stir.

Refrigerate overnight. 

In the morning, the oats are softened to perfection. No cooking required. If you forget the night before, microwaving works too.
You can also microwave (for 80 seconds - depending on your microwave) or add hot water and steep for an instant cup of oatmeal.
