Put baking sheet with pastry on a work surface and unfold any edges so pastry is flat. Spread applesauce over pastry, leaving a 2-inch border, and top sauce with sliced apples, mounding slightly. Fold edges of dough over filling, partially covering apples (center will not be covered) and pleating dough as necessary. Dot apples with butter, then brush pastry edge lightly with water and sprinkle with remaining 1/2 tablespoon granulated sugar. Bake galette in middle of oven until pastry is golden and apples are tender, 40 to 45 minutes.
