Preheat oven to 425F degrees and line a baking sheet with parchment paper, set aside. Place asparagus in a small dish with 1/4 cup water; microwave on HIGH for 1 minute, then drain. Unfold pastry and cut into 4 equal pieces; place on prepared sheet. Top each pastry piece with equal amounts of herbs, chicken, asparagus and cheese, in that order. Fold in 2 points of each pastry bundle and jpress to seal. Bake for about 16-18 minutes or until pastry is golden brown.
