Heat oven to 350ºF. Divide dough into 4 pieces. Place 1 dough piece between 2 lightly floured sheets of parchment paper; roll into 6-inch square. Discard top sheet of parchment paper. Cut dough into 4 smaller squares. (Do not separate squares.) Cut large square diagonally in half twice to form 8 triangles. Invert onto baking sheet; remove and discard parchment paper. Repeat with remaining dough.
