Since you’ve travelled enough to have a greater understanding, could you share with us your knowledge of a culture that makes flatbread but doesn’t put stuff on top of it? Where is that culture? What is their flatbread called?
Imeretian (Imeruli) khachapuri
Because it's in it, heh!
And BTW adjarian khachapuri is technically a pizza too.
