Puff Pastry Chicken Bundles

Directions

1. Preheat oven to 400°. Cut a lengthwise slit in each chicken breast half to within 1/2 in. of the other side; open meat so it lies flat. Pound with a meat mallet to 1/8-in. thickness. Sprinkle with salt and pepper.
2. Place 5 spinach leaves on each chicken breast half. Spoon a scant 2 tablespoons of cream cheese down the center of each chicken breast half; sprinkle with 1 tablespoon walnuts. Roll up chicken; tuck in ends.
3. Unfold puff pastry; cut into 8 portions. Roll each into a 7-in. square. Place chicken on 1 half of each square; fold other half of pastry over chicken. Crimp edges with fork. Combine egg and cold water; brush over edges of pastry.
4. Bake on a greased 15x10x1-in. baking sheet until a thermometer reads 165°, 20-25 minutes.
