My friend, Susan Howell, recently asked me for a cookbook recommendation. She wants to expand her fairly limited repertoire in a healthy direction, with recipes that "don't have long lists of ingredients."
This is the one I suggested: The Simply Healthy Lowfat Cookbook: Over 250 Lowfat Recipes Rich in the Antioxidant Vitamins That Keep You Healthy by Kate Slate (Editor), Lisa Koenig (Photographer). It's published with the Berkeley Wellness Letter, a reliable source of nutritional info. I've made everything from main courses to desserts from this book, with good results.
