Meanwhile, in a large bowl stir together brown sugar, flour, and nutmeg; add chopped apple and walnuts. Gradually stir dried fruit mixture into apple mixture.
Transfer filling to pastry-lined tart pan. Top with pastry strips in lattice pattern. If desired, brush pastry strips with milk and sprinkle with sugar. Bake about 45 minutes or until fruit is bubbly and pastry is golden. Cool on wire rack. To serve, remove sides of tart pan.
