“…some fava beans and a nice chianti.”

Cooking question for you: I bought some fresh fava beans at the market today. I thought I could just boil them like lima beans, but they have this tough shell sort of thing around the pod. What am I supposed to do with this…do I peel them? It is rare that a vegetable stumps me so.

p.s. I did try googling fava beans, and all I got back was a bunch of Hannibal Lecter references.
