Preheat oven to 350 degrees. In a large bowl combine the chicken, vegetables, soups, dill, salt and pepper. Gently stir until well combined. Spoon into individual baking dishes. Top each baking dish with a piece of puff pastry, enough to cover the chicken mixture. Brush the top of puff pastry with egg wash. Bake in 350 degree oven for 20-25 minutes until bubbly and the pastry is brown on top.
