Book excerpt: Eating vegetarian doesn't have to mean giving up the satisfaction of mouthwatering, stick-to-your-ribs comfort food. This book recasts classic all-American ''meat and potatoes'' food in a healthier role, from family-style foods to gourmet specialties to ethnic favorites. With recipes ranging from Tapenade-Stuffed Red Potatoes, Cajun Red Bean Burgers, and Eggplant Teriyaki to Total Chocolate Eclipse Cake and Pecan-Studded Chocolate Brownies, The Vegetarian Meat & Potatoes Cookbook will revolutionize the way you think about vegetarian food.
