In a bowl, coat the apple pieces with maple syrup. Set aside.
In a separate large bowl, mix together the pork, spices, salt, pepper, bread crumbs and egg. Set aside.
Roll out the puff pastry into two rectangles: one about 25 cm X 13 cm ( 10 in X 5 in ) and one wider ( 25 cm X 30 cm [ 10 in X 12 in ] ).
Line a baking sheet with parchment paper and place the smaller rectangle of dough on it.
Shape the meat mixture into a loaf and position it on the dough, leaving a 1.25 cm (1/2 in) border around the edges. Brush this border with some of the egg wash.
Cover the meat with the larger rectangle of dough and seal the edges with a fork.
Brush the entire surface of the dough with egg wash, and make small slits in the dough with a knife.
Put the apple pieces in a roasting pan. Bake both the meat loaf and the apples in the centre of the oven for 45 minutes. Serve together.
