Preheat oven to 400°F. Line a cookie sheet with parchment paper or silicone baking mat.

Stir together brown sugar, cinnamon and nutmeg. Set aside.

Slice apples 1/16-inch (1mm) thick. Place in a large bowl and toss with lemon juice and sugar mixture.

Roll out pie crust to a 12 or 13-inch circle and place on prepared baking sheet.

Arrange the apples (without any juices) in the center of the pie crust circle, leaving a 2-inch border.

Fold up the edges gently and place over the pears, overlapping as necessary. Brush with egg wash.

Bake 28-32 minutes, or until golden. Let cool to room temperature before serving.

Serve room temperature or warmed, plain or with ice cream. Store in refrigerator. Can be frozen for up to 2 months.
