In a medium saucepan over medium-low heat, heat apple filling until warm. Stir in blueberries and vanilla; cover to keep warm. In a small bowl mix sugar and cinnamon until combined; set aside. To assemble: Brush each tortilla generously with melted butter; sprinkle with sugar-cinnamon mixture and place 1/6 blueberry-apple mixture down center. Fold bottom of the tortilla to partially cover the filling; fold in side to enclose filling completely. Garnish with additional blueberries and confectioners sugar, if desired
