Thaw the pastry sheet at room temperature for 40 minutes or until it's easy to handle. Heat the oven to 375 degrees F. Lightly grease a baking sheet.

Stir the brown sugar, flour, cinnamon and nutmeg in a medium bowl. Add the apples, pecans and butter and toss to coat.

Unfold the pastry sheet on a lightly floured surface. Roll the pastry sheet into a 15 x 10-inch rectangle. Brush the pastry sheet with water. With the long side facing you, spoon the apple mixture on the pastry to within 2 inches of the long sides and to the edge of the short sides. Starting at a long side, roll up like a jelly roll. Cut the pastry roll into 12 (1 1/4-inch) slices. Place the slices 2 inches apart on the baking sheet.

Bake for 15 minutes or until the pastries are golden. Remove the pastries from the baking sheet and cool on a wire rack. Sprinkle with the confectioners' sugar.

You can substitute chopped walnuts for the pecans if you like.
