Some call it fugazzeta. I'm not sure what the difference would be between the two names.
It is bread with about two and half whole onions chopped and placed on top.
I have always liked onion on my pizza, but this is ridiculous!
I have actually tried it and it's pretty good if the onions are somewhat browned on the tops as in the foreground.
Something new for those who don't have it available in the country of your covid.
