9x13 Chicken Pot Pie

I had some leftover grilled chicken breasts and needed a way to use them. I also had bought a new product that I wanted to try, those little tubs of Knorr stock. Hubby has always loved when I make pot pies so he was quite happy when I told him what I was going to make. He groaned after eating, because he had eaten too much, I guess that is a good sign, right? Seriously though he said it was really good.
