Traditional “Kibin” from Ukraine Tatar. Served with chicken stock.

Visually, at least on the outside, it looks something like a Stottie, Oggie or Pastie from the farming/mining areas of the UK. I always find it fascinating to see the convergent evolution of this sort of food - edible with one hand, hot and filling, with a crust that can be discarded if hands are filthy, or et if not.
