Deceptively Delicious by Jessica Seinfeld was one of the first books I read when I was beginning to learn more about cooking and nutrition.  (The Family Nutrition Book by Dr. William Sears was another one if you’re just getting started.)

I remember looking at her recipe for brownies with spinach and wondering if you truly couldn’t tell there was vegetables in them.  This was about a year before I discovered green smoothies and did not yet understand the invisibility powers of spinach when prepared the right way.
