I've found this recipe in today's newsletter from Farm Fresh to You. I happened to have arugula and lots of fava beans that needed to be taken care of. I didn't need more than that to get started!
Fava Bean Spread
1. Shuck about a pound of fresh favas, parboil for 3-4 minutes, and peel off the tough outer skin.
2. Put them in a processor with a chopped clove of garlic, about a cup of fresh Italian parsley, arugula, or a combination of both, a tablespoon of good red wine vinegar (or lemon juice or any other good vinegar) and a healthy drizzle of good olive oil.
3. Process until you get a coarse puree, adding more oil if necessary (or mash everything together with a mortar and pestle). Salt to taste.
