The book is called "The Sneaky Chef" and it's a great way to sneak some great veggies into your kids' food. I might get it just to use it for myself. The only thing is, it requires a food processor to be able to puree the food, and I don't have one. I'm sure I can get a secondhand one somewhere really cheap.
