definitely Pyzy topped with some tomato-meat sauce
I agree - the picture looks like "pyzy" (called so in Poznań/Wielkopolska - in some other regions they are called "pyzy drożdżowe", because for us in Mazowsze (Warszawa - Łódź) "pyzy" are potato dumplings with or without filling, the difference between pyzy without filling and kopytka is that for kopytka you use only cooked potatoes, while for pyzy both cooked and raw)
Pyzy (drożdżowe) are yeast-based, the dough is the same (or very similar) like for Polish donuts (pączki), but of course you don't add marmolade/jam and you don't cook them immersed in oil (like pączki), but on steam
