I found a great site/blog called Two Azorean Chicks! Check out their blog! They have lots of great recipes. This is how the 2 Chicks describe this recipe. "Salty, crunchy and tasty! Go figure we eat beans as a snack too. You can find these at your local Portuguese market, but they are also easy to make. So give it a try. " The 12 hour prep time is just soaking the fava beans overnight.
