Johnathan Kauffman is a James Beard Award-winning writer. His new book is "Hippie Food: How Back-to-the-Landers. Longhairs and Revolutionaries Changes the Way We Eat." We discussed the rebellious nature of the original organic food movement, why things like hummus and whole grains were considered exotic and extraordinary, and why the "farm-to-table" movement likely would never exist if not for the original hippie food co-ops.
