I like you tube videos on this sort of thing. Gino D'Acampo. This Neapolitan born British celebrity chef has a series on the food of Italy, southern Italian heavy, but which is fun.
He has two on Sardinia. I think it's interesting particularly because he goes all over Sardinia interacting with the locals, including to Orgosolo, which is that isolated area of Sardinia which is such a good match for EEF.
