While I do enjoy anchovy pizza when I eat it, I only seem to be in the mood for it about twice a year. On the other hand, it's one of the standard proteins I add to salads. And, of course, as one of the ingredients of worcestershire sauce.
A few months ago, when I was getting my hair cut, someone ordered from a local Italian restaurant a dish which was essentially mozzarella cheese and anchovies on pieces of Sicilian Pizza crust-like bread. The person who ordered it didn't like it, nobody else would touch the dish because of the anchovies, so I volunteered. Great stuff.
One time, at a pizzeria, I saw a Sfincione on display in the window (a Sicilian pie made with bread crumbs, tomatoes, onions and anchovies). I walked in and asked about it; turns out that it was the first time they had tried it, and they were pleased that a customer actually knew what it was, so they gave me a free slice in exchange for my opinion (oddly enough, this sort of thing seems to happen to me a lot. I think I'll start a new thread).
