In large bowl, mix filling ingredients except milk and coarse sugar; toss gently to mix. Spoon into crust-lined pie plate. Cut second crust into about 2x1 1/2-inch rectangles. Lay in straight rows across filling, placing one corner over the other, leaving about 1 inch between rows. Place remaining dough rectangles around edge, overlapping to fit. Brush with milk; sprinkle with coarse sugar. Cover crust edge with 2- to 3-inch-wide strips of foil to prevent excessive browning; remove foil during last 15 to 20 minutes of bake time.
