Pizza is essentially a tartine. So by logical deduction a pizza is an open faced grilled cheese sandwich.

A cheese sandwich with tomato and no mayo/mustard. But I heard they do put mayo on pizza in Japan, so they really get it.

Japanese Domino's

What is a TARTINE 🤣 for some reason you saying that word cracks me up

Pizza sandwich is like a Panuozzo.
