I have never seen this cookbook but enough blogging moms have recommended it to me that I feel I can give it a thumbs up!
Deceptively Delicious  is a cookbook designed to sneak veggies into your kid’s food! Amazon describes it as:
“Her book is filled with traditional recipes that kids love, except they’re stealthily packed with veggies hidden in them so kids don’t even know! With the help of a nutritionist and a professional chef, Seinfeld has developed a month’s worth of meals for kids of all ages that includes, for example, pureed cauliflower in mac and cheese, and kale in spaghetti and meatballs. She also provides revealing and humorous personal anecdotes, tear–out shopping guides to help parents zoom through the supermarket, and tips on how to deal with the kid that “must have” the latest sugar bomb cereal.”
Right now on Amazon you can get Deceptively Delicious for $6.93 !
