Linda Long is not a food writer, but an accomplished food photographer as well. In her new book, “Great Chefs Cook Vegan,” she talks with some of the greatest chefs in the U.S., and gets them to come up with dynamic, delicious (and from a few, rather complicated) vegan dishes that would have previously been unthinkable. This book really proves that vegan cooking is a cuisine in its own right, and has finally been elevated to rock star status and high acclaim among the nation’s culinary elite. I spoke with her on her recent tour through Chicago. 2009-02-12 Vegan
