Thaw the puff pastry in the refrigerator (keep covered with parchment paper)
Mix the egg with the milk to make egg wash
In a large bowl, mix the apples, sugar, cinnamon, chocolate and almonds.
Lay out the sheets of puff pastry horizontally. Lightly flour and roll out slightly with a rolling pin.
Spread the apple filling out horizontally toward the front of the dough leaving approximately 1” border at the bottom of the dough.
Using a pastry brush, brush the dough with egg wash covering all areas except those covered by the filling.
Fold the dough over the filling to form a strudel and press down on all edges.
Using a small knife, poke small holes into the top of the strudel and then press any air out of the pocket.
Brush outside of the strudel with egg wash.
Bake in a 400 degree oven until brown, cool and slice.
