Mix the meat, parsley, breadcrumbs, onion, salt and pepper in a bowel.
Cut the potato as if you are going to make a thick slice but do not go all the way to the end.
Cut another thin slice, but this time cut all the way through.
Now you will have a potato slice that opens like a sandwich.
Stuff each pocket with the meat mixture.
Beat the eggs with paprika and a pinch of salt.
Dip the potato in the eggs then cover with flour.
Fry in oil.
Take it out when it is golden brown and make sure the potato and the meat are done.
Serve as is or prepare some tomato sauce then pour on top.
