Spread jam to within 1/2-inch of edge. Add pistachios to remaining dough. Drop by spoonfuls over jam to cover. Bake 35 minutes until top is golden brown; cool. Cut into squares.

Serving Tip: For a special dessert serve warm 3-inch square bars topped with whipped cream and additional chopped pistachios.
