Heat oven to 375°F. In medium bowl, mix pecans, brown sugar and butter. Spread in bottom of 9-inch glass pie plate. Place 1 pie crust over pecan mixture, allowing excess crust to hang over sides. In large bowl, toss apples, granulated sugar, flour, cinnamon and nutmeg. Spoon apple mixture onto crust, packing tightly and mounding in center. Unroll second pie crust over filling; press edges together, fold under and crimp. Cut slits in several places.
