I struggle with hot grain cereals for breakfast. I can't eat much of them and so I quickly hunger again afterwards.
The best way for me to do oatmeal is as a muesli. Uncooked oatmeal, plain yogurt, fruit--fresh and dried, sweetener as needed (honey most often) perhaps some vanilla or similar extract. Let it sit overnight in the refrigerator to soften and blend flavors. If I need some warmth, I suppose that would be what Hot Chocolate is for.
