This is a bohemian side dish.
Usually serves with gulash but goes really well with any kind of stew.
You use cubed dried white bread rolls and eggs and milk and butter and then shape it together in a cloth napkin and cook that.
You can slice it and fry it a little to make the slices crunchy.
Looks like a big sausage.
Just an observation. I want to try this, looks good!
