As a vegetarian who loves to cook, I have lots of veg or veg-friendly cookbooks, but this one is my absolute favorite. I trust it completely-- every recipe is delicious. My favorites include the light quiche-like vegetable tarts (I started with the tomato and chard tart recipe, but then branched out into mushrooms, broccoli, leeks, etc, as my mood strikes) and the broccoli salad with chili lime basil dressing. The simple stir-fry tofu made for this salad is the absolute best tofu I've ever had-- the only trouble with it is how hard it is to refrain from eating it so that enough ends up in the salad!
A "Zen" approach to cooking? The book features an essay by Eido Shimano roshi, and the author is informed by her experiences cooking for the sangha at Dai Bosatsu monastery, but this book stands most prominently as a fine vegetarian cookbook, light on dairy ingredients and hard-to-find items. The recipes are clear, uncomplicated, and my own "success" rate with them has been very high.
The book's sections are organized into breakfast ideas, an excellent chapter of soup recipes (check out the minty lentil soup - a lentil soup primavera?!?), mexican ideas, pizzas!, great salad ideas, and desserts. Crepes and polenta are also introduced to the beginner or near-beginner.
