Ok, so yes, this looks like Israeli Cous Cous or It is similar to North African Berkoukes. It’s pretty clear that someone in the Middle East or North Africa got in a boat and went for a trip, and eventually landed in Sardinia. But in Sardinia they liked it better toasted, so that’s what they did, and they called it their new thing, fregola or fregula. Yes, it will go great with any recipe that you have that calls for Israeli Cous Cous. It has a diameter of approx 5 mm.
