@NaomiSkarzinski OMG, it's a total Sicilian thing. A few ways to do it -- as mentioned, with shaved red onion, olive oil, fresh mozza, rosemary.

But also -- ricotta, thin leek, pancetta, pistachio, salt, fresh mozza

And in Bulgaria I had an amazing Sicilian dude's pizza with italian sausage, ricotta cream base, mozza, and pistachios.

I also use walnuts just because they're cheaper. Nuts are authentic on Italian pizzas -- we just don't do it a lot here. :)
