Another book in a similar vein is Simply in Season, I don't have a copy, yet, but have heard good things about it. The book I go to for seasonal vegetable recipes is The Victory Garden Cookbook. Whatever strange veggie I bring home from the farmer's market can be cooked up with this book. It's all-inclusive! It even includes advice about growing your own garden.
Another of my go-to's is "Family Feasts for $75 a Week or Less". Mrs. Ostyn feeds her family of 12 with these real life, healthy, basic recipes. I love that the recipes are based on things that have been tried and found true! You can visit her blog at Owlhaven. I wanna be like her when I grow up!
The World's Healthiest Foods is a great value. I bought it at Costco for about $20. This a full nutrition course along with a cookbook. It's a major work and should be on everyone's shelf, and pulled out often! I use it for school, for recipes and for learning new cooking methods. Do ignore the inclusion of soy as a healthy food. I'm sure the author will repent in due time.
