Is Foul Fair? (Or what is this mystery bean) I came across this at my local hypermarket, and I'm wondering what it is, and what one can do with it.

If it isn't obvious from the picture (Bigger version here https://i.stack.imgur.com/M4TKG.jpg) Its a dark brown bean, roughly the size of a coffee bean, and a medium dark brown colour. The specific manufacturer typically sells iranian/middle eastern herbs, so its likely to be from that area. 

What is it, and how generally does one use this?
These are fava beans, the term "foul" (uncommon transliteration) on the pack hinting at a dish that these beans are typically used for:

A ful, a stew-like dish of cooked and spiced beans from the Middle East.
