I’ve been eating a lot of oatmeal mostly because I’m cheap rather than for health reasons. ;-) Since I’m also lazy and don’t have time to cook in the morning (and hate dealing with the microwave), a lot of the time I do muesli instead of oatmeal. The night before you put oatmeal, dried fruit and nuts if you want ‘em, maybe some cinnamon and some sweetener in a container, add milk to cover, and let it sit overnight.
Tasty. Not low-carb, of course, but probably pretty healthy. And all I have to do is grab it as I run out the door.
To clarify: let it sit overnight in the fridge.
