Unfold puff pastry sheets on a lightly floured surface. Roll each sheet into a 12-in. square. Spread pesto onto 1 pastry sheet to within 1/4 in. of edges. Sprinkle with cheese. Top with remaining pastry, pressing lightly. Cut into twelve 1-in.-wide strips. Twist each strip 4 times. Place 2 in. apart on parchment-lined baking sheets, pressing down ends.
Bake 12-15 minutes or until golden brown. Serve warm.
