Stir well to mix everything and to help break up the cream cheese. The chicken will start shredding at this point but you may need to shred it lightly with a fork.
Serve the mixture over a bed of cooked egg noodles, or mix them in entirely.
You can easily substitute with chicken thigh meat.
You can omit the Worcestershire sauce or Dijon mustard if that's what you prefer, but the two really help bring a lot of flavor to the plate. Feel free to add a splash of dry white wine for an even richer sauce.
