Kale is one of the few local greens that's available almost year round. This week on the Local Food Report, Elspeth Hay talks with author Cathy Walthers of West Tisbury about her new cookbook Kale, Glorious Kale. They cover everything from the nutritional benefits of the green to kale varieties and recipes—including some that might come as a surprise.

You can see a picture of some of the most common local kale varieties and find Cathy Walthers' recipe for Kale Granola on Elspeth's blog, Diary of a Locavore.
