Yeah, I think most leave them out. But its in the original recepie

And some olives, capers and garlic

Isn’t it enough to have them in the dressing?

Don’t forget to preheat the steel on max temp for about an hour or so

You could get pretty good results with a pizza steel. Crank the oven to max and preheat the steel for about an hour. Then you get 2 pizzas with leoparding on the bortom. After that the heat in the steel is gone and they do not turn out so great anymore.
