Using a hand mixer, beat cream cheese and sour cream until well combined. You can combine it by hand if your cream cheese is soft enough. Stir in salt, pepper, onion, chives, and diced chicken
Using Pillsbury crescent rolls, take 2 triangular rolls and push together at perforated seam to make into a square. Make sure you seal the perforations well so your filling doesn't come out. Put about 3 tablespoons of chicken mixture in the center of each square. Fold the dough corners to the center over the chicken mixture forming a pillow.
Dip each pillow in melted butter on both sides. Roll in bread crumbs on both sides. Shake excess crumbs off. Place chicken pillow on cookie sheet and bake at 350 degrees for 20-25 minutes.
Make gravy by mixing one package of chicken gravy mix, one can of cream of chicken soup and 3/4 can of water in a small pot. Mix together and heat until warm. Serve chicken pillows with gravy poured over top.
