I know this is a long shot, but I'm just back from Italy and one of the most incredible dishes I had was an artichoke omelette from a tiny restaurant called Sostanza.
This was served as an appetizer and it was fluffier then an omelette, but not as light as a souffle. The artichokes were fresh. I've included a link with the picture. I would be thrilled if someone knew how to make this. (btw, I don't think there was any cheese in it)
