A little bit of freshly grated Pecorino Romano or Parmigiano Reggiano over some chopped fresh Roma tomatoes, garlic, olive oil and some fresh oregano. That’s all.

 
 
I also agree  …  That is a great pizza.  Though I might drop the oregano and add basil.  If the tomatoes can be San Marzano tomatoes, then that’s a bonus.
