Jos, here in Australia, rolled oats are whole oats rolled flat and they need slow cooking, but quick or instant oats are finely milled - I think - and don't need slow cooking.

When I was working I used to put rolled oats and a couple of other things e.g. chia seeds and psyllium, with dried fruits and a bit of milk in a cup sized container, add some boiling water and then half an hour later when I arrived at work I just topped it up with more boiling water and I had my porridge ready to eat. The oats had become porridge in the half hour. Easy!

I've tried adding psyllium to pancakes but it goes gluggy - not appetising - but I have also whizzed oats in a blender to make an oat flour and added about a cup of that to pancakes with ordinary flour and it worked well.
