>more like a succulent bread with cheese and nice flavour enhancers.
Yup that's pretty much it. It uses focaccia bread instead of regular pizza dough, and lots of high quality cheese (which is the main star of the show, if the cheese is not high quality then it sucks).
Basically it's a style of pizza that evolved from focaccia, someone had the idea of put cheese and onion toppings on pic related, creating the fugazza, and then someone else had the idea of stuffing cheese in the middle of the dough as well creating the fugazzeta. Italians probably consider the whole thing an aberration kek but it's delicious.
>do people sometimes ketchup on it?
No, the whole point is to taste the cheese and the dough which is also special as described, but I've seen it with ham and tomato sauce occassionally.

I'm gonna look for this around, we have some German-style bakeries (like Hausbrot) that may sell it. Or just try cooking it myself, sounds great.
