I have two great books along green-living lines that I think you should check into. The first is The Complete Idiot's Guide to Vegan Cooking by Beverly Lynn Bennett of Veganchef.com and Ray Sammartano.
This is one of those essential books for vegan living. With 240 delicious recipes and tips galore, you may not need another book about vegan cooking. I absolutely love the formatting of the book. There are 6 parts, each prefaced with a cute little cartoon (one of my daughters kept leaving the book open to Part 6 because she thought the cartoon was so funny) and 22 chapters in total. That's a lot of information and a lot of great recipes.
The 'extra information' boxes are so helpful; broken down into Thyme-ly Tips, Soy What?, def-i-ni-tion, and Sour Grapes, they're placed just where needed to add that little extra bit of info necessary to that particular recipe. I've learned quite a bit from those little boxes!
This is geared toward the beginner, but the recipes are so terrific that I would recommend this for even the seasoned vegan.
The second book is Eco-Friendly Families by Helen Coronato. I love this book! I've learned more about green-living and recycling than I ever thought possible. It's written in a very approachable way and full of family-friendly ideas for living as ecologically responsible as possible.
My favorite part are the Five-Minute Makeover boxes throughout the book. They are the small ideas that help you to make a big impact without taking much time at all. I also think the first chapter, "Taking Inventory: Getting Ready to Go Green" is brilliant. Helen helps you to figure out where you are, where you want to be and just how to get there in the most painless and simple way you can.
She causes you to think and re-think about your family's impact on our earth and how you can help to keep your footprint small. It really is for all ages. The crafts at the end of the book are wonderful and the resources listed are all you'll need to send you and your family on your way to greener living.
You can purchase both of these books at Amazon.com.
