Preheat oven to 400 degrees F. Grease a large baking or cookie sheet.
In a medium-size bowl, combine feta cheese, parsley, olive paste, and egg whites.
Unfold (1) one of the pastry sheets on a lightly floured surface, keeping the remaining pastry sheets in the refrigerator. Roll into a 14x16-inch rectangle with a floured rolling pin.
Cut crosswise into halves. Spread half the olive mixture over one (1) pastry half. Top with the remaining pastry half. Roll gently with a rolling pin to seal the layers together.
Cut the pastry crosswise into 1/2-inch wide strips. Arrange the strips 1-inch apart on prepared baking sheet, twisting each strip 3 or 4 times. Bake
approximately 12 to 15 minutes or until puffed and light brown. Remove from oven and let cool on a wire rack.
Repeat the process with the remaining puff pastry and remaining olive mixture.
Serve at room temperature.
Store in a tightly covered container.
Makes approximately 56 bread sticks.
