Cascadian Farms organic brand of cereals and granola bars. Simply unreal. So much better for you, and they seriously taste great! Yes, I have to get the version of their cereal marked "kids" in order to get my Cinnamon Toast Crunch knock-offs. But, it's worth it. It's way more filling per calorie ('cause it's REAL food), and it tastes great.
Make the leap. It's not a big one.
