Fava beans (a.k.a. broad beans) are creamy in texture and flavourful enough to headline a simple meal. Simple in the sense of "oh, I just whipped this up," but sophisticated too. Use your very best olive oil; serve the prosciutto on the side or crumbled on top. Salty, tangy Pecorino Toscano makes a perfect addition, but for a bolder flavour you could shave on some Pecorino with truffles (Pecorino Tartufo).
