I used to love flavoured instant oatmeal. Now, I've come around to the real stuff, so to speak, and it's soooo much cheaper! I pick up a bag of rolled oats from Aldi or Lidl for about 49p or something ridiculously cheap like that. I add half a cup of those to a cup of skimmed milk and cook on the stove top until its thicker and creamy - about 5 minutes or so, and add in whatever else I want while it's cooking - vanilla extract, brown sugar, maple syrup, cinnamon, fruit, nuts... you name it. You can use whole milk or other types, but it gets pretty rich, I find skimmed milk makes it more filling from the protein, not too rich, and is better for the diet... lol.
Honestly, I'd never go back to the packet stuff now!

And I was a DIE-HARD Quaker maple and brown sugar instant oatmeal fan.

I think I started about 5 threads about how much I was missing it... haha!
