Oatmeal! Buy some old-fashioned oatmeal. Avoid the instant stuff, since it has fewer nutrients and less complex carbs/fiber (making it less filling AND less healthy.)

As you're bringing the recommended amount of water to a boil, add a pinch of salt and a chopped banana to the water. Cook the oatmeal until it's tender (~5mins.) Or add some brown sugar and cinnamon instead of the banana.

Omelets. Mix one or two whole eggs (including yolks) to three, five ,ten, or however many egg whites you want (if you do this regularly, consider Egg Beaters or a similar product--it's all egg white, despite the fake color.) Heat a pan hot with just a little oil, and quickly saute mushrooms, bell peppers, spinch, or whatever sounds good. A little cooking brings out some of their flavor. Then turn the heat off (or down to low), add the eggs, and keep stirring just until it sets. Add an herb or two just before the omelet finishes.

Or as an alternative omelet, simply add salsa with the eggs. Simple but good.

And there's always ground beef. It doesn't sound like much, but it scratches the old caveman instinct in all the right ways. Just buy some extra-lean ground beef, add something for flavoring like rooster sauce or Worcestershire, a little salt and pepper, and eat it plain. If you find the right seasoning, it's a nice simple dish.
