Gotta go with Trix, they're not just for kids!
My wife gave me crap for eating 'unhealthy' cereal. She eats some sort of organic Kashi granola type stuff. Turns out my Trix has more vitamins and less bad stuff per serving. Granted, that's because the percentages are calculated by weight and the serving size is volumetric, so the heavier Kashi cereal takes a hit... but still, I won that fight
