All I could find was that the version I know comes from Székelys of Bukovina. Maybe it’s convergent evolution of resourceful people🤷‍♂️

Just re-read the tale, it’s actually a bit similar, it has sausages (kolbász, much closer to chorizo than the english type), potatoes and rice.

Ha! We have a very similar folk tale in Hungary about a soldier returning from war with a rock, asking an old lady to cook the “stone soup”, asking for more and more legit ingredients.

Literally uplifting, figuratively not so much with the war and all
