I've been using these BetterOats oatmeal packets for breakfast almost every day lately. I love the "Organic Raw" ones, which have no added sugar or flavoring, just good-for-you whole grains. I sometimes throw in a few raisins or nuts during the last 20 seconds of microwaving, just to add a little sweetness and texture.
The best part about them is that once you've torn open the packet and dumped the oats into a microwaveable bowl, you can use the waterline printed on the packet to measure the correct amount of water into your oatmeal. No need to get a measuring cup out or guesstimate. What a good idea! Available at Target.
