This might sound silly, but I love the book "Feed Me, I'm Yours!" by Vicki Lansky. It's a collection of healthy snacks and easy meals for children, but everything in it is really good! And it is all super healthy real food. I use it all the time for my kids and myself.
Have you tried Tosca Reno's books? The eat-clean diet and also The Butt Book have awesome suggestions and lots of pictures. They are very inspirational. She also has a cookbook coming out this fall I can't wait to get!
