Nowt to do with bread making but...

No need for fine milled oats for anything. Any porridge oats can be cooked in 3 minutes in the microwave or 5 minutas in a pan. I use the former to save washing up. No need to cook at all really. Roman soldiers used to munch on a handful of dry oats for extra energy while marching. If you don't fancy that, just soak them overnight.
