Preheat the oven to 375F and line a baking sheet with parchment paper.
Press one of the pie crusts into the base of a 9 inch pie dish. With the other pie crust either cut strips to make a lattice or use pastry cutters to cut out shapes and lay them on the parchment paper until ready to use.
In a bowl stir together the apples and pears, sugar, flour, lemon juice, cinnamon and ginger until combined. Spoon this mixture into the pie crust then drizzle with the caramel sauce.
Lay the lattice or pie crust cut outs on top of the pie filling. Brush with the beaten egg and sprinkle with the turbinado sugar.
Freeze for ten minutes.
Place onto the baking sheet and bake for around 45 to 55 minutes until the crust is golden brown and the apples and pears are tender.
If the pastry is becoming too dark, cover with aluminum foil.
Allow to cool in the pie dish then serve with additional caramel sauce.
