I am a breakfast person. I know there are a lot of non-breakfast types but not me; love it. When I can't have tea and toast, or just want a change, oatmeal is my go to.
My oatmeal is a simple kind of thing - bring old fashioned rolled oats slowly to boil. If it looks too dry, add a bit more water, if it's too wet, just keeping on stirring.
Once the oats are cooked, put them into your bowl. Top them with some jam (or marmalade, swoon) and a splash of cream.
Cheap, fast, filling, good for you and the leftovers make a great lunch.
