Soak the bread in cold water for 5 minutes.
Break the egg into a bowl and beat in the nutmeg, pepper and a little salt with a fork.
If your bacon is very salty, omit the salt from the filling mixture.
Squeeze the water out of the bread and mix this into the egg.
Combine this mixture with the pork and mix well by hand.
Put a bacon strip on the worktop then lay another bacon strip next to it, long edges touching. Thread a third strip over the first strip and under the second, so you end up with a square.
Repeat until you have 16.
Shape the ground pork mixture into 16 large rectangular meatballs.
Put a meatball on each trio of bacon strips, then fold the ends of the bacon strips over the filling and press them tightly closed.
If you like, you can dip the 2 short ends in dried parsley for a festive look.
Fry the slavinken in butter or lard if necessary (depends how fatty the bacon is) for about 5 minutes.
Flip them over and cook for 5 minutes on the other side or until the core temperature is 160 degrees F (70 degrees C) then serve hot.
