I would highly recommend "The Natural Gourmet" by AnneMarie Colbin. I am borrowing this book from a dear friend of my mom's, who lent me a number of cookbooks. This cookbook is my favorite from the stack - is a goldmine of incredible recipes that are easy, nutritious, delicious, and based on vegetables, legumes, and grains. I don't have to substitute a darn thing in half the recipes, which given my current dietary restrictions, is incredible. Pulling from various food traditions, she provides a lot of useful information about food combining, flavors, and the five elements theories, discusses different ingredients, and gives suggestions on kitchen tools and equipment. Most of all, I love her soup recipes - I am a soup person, I could (and, basically, do) live on soup. This weekend I made three batches of soup from her book with my purchases from the farmer's market: carrots, turnips, onions, squash, parsnips, to name a few. All three were delicious: Hungarian Asparagus Soup, Squash-Carrot-Parsnip Soup, and Japanese Red Bean Soup. My freezer is bursting and ready for winter.

Her recipes do use some gluten containing grains (wheat, barley), and she does use butter, natural sweeteners, and other items that are on my no-no list. But, some of those can be substituted. And besides, no cookbook will ever match your needs 100% on every recipe. Overall, this cookbook is a winner, I need to get my own copy! She also has written other cookbooks that sound just as enticing.
