Fain is a nutty, peppery flatbread (related to the italian flatbread farinata) made with garbanzo bean (chickpea) flour. Fain is hugely popular in both argentina and uruguay. It's often served as an accompaniment to pizza (pizza a caballo). This version of fana-topped with chorizo sausage, blue cheese and spinach-makes a great appetizer, and is a gluten-free alternative to regular pizza. Fain is very quick and easy to make, and you can find garbanzo bean flour at many natural food stores.
