The night before, with a knife remove the heads (the black part) from the Fava beans.
Put the fava beans in a pot, cover with water, about 1" over the Fava beans and add a pinch of salt. Let them soak overnight.
In the morning, put the Fava beans on the stove and cook at very low flame for about two hours (depending on size of Fava beans). Taste and shut off flame when they are Al Dente.
While the Fave finish cooking, cook the Arborio rice to an Al Dente consistency.
Combine the Fava beans and the rice in a serving platter.
Slice the onion and saute` it in 1/2 Cup of EV olive oil. The onion has to turn golden brown. Pour over all the ingredients, add some Peperoncino as desired and serve.
