Cook meat in salt water until it is tender.
Remove meat from broth; add minced onion and
parsley to broth. Bring to the boiling point
and add alternate layers of cubed potatoes and squares of dough.
Add meat and stir through pot pie.
To make dough, beat egg and add milk. Add flour to make a stiff dough. Roll out paper thin and cut into 1-inch squares.
Keep broth boiling while adding dough squares in order to keep them from packing together. Cover and cook for 20 minutes, adding more water if needed.
