Boil chicken breasts until done. Remove from pan and break/cut into bite-sized pieces. Make stuffing by package directions. In a medium sized bowl, mix together cream of chicken soup and sour cream to taste. If you like layers, put chicken on the bottom, spread stuffing on top of that, and then add soup and cream mixture to the top. The other option is to mix it all together. Bake at 350 degrees for about 20-25 minutes.
