The first thing you'll need to do is boil the chicken. Bring a pot of water to boil, add a pinch of salt to the water. Put the chicken breasts in and cook for 30 minutes. When it is done, pour water the chicken has been cooking in, reserve 1/3 cup of the liquid.
Put chicken back in the pan and shred with two forks. Add the reserved cooking liquid back in the pot with the shredded chicken and add the can of the cream of chicken, reserve 1 tbs.
Preheat oven to 350.
Add the bag of frozen veggies and cheese to the pot, put a pinch of salt and pepper in and combine all ingredients by stirring a few times.
On a cookie sheet put one of the pie doughs (if it is not in a dish then lay it out in a pie dish). Fill will the ingredients from the pot (the chicken/veggies cheese) and lay the other pie dough on top and pinch the crusts together (really pinch together so that the pie doesn't spill out.)
Combine the 1 Tbs remaining cream of chicken with 1 tbs water and brush it on the top of the pie. Cut a few slits on the top/center. Bake for 55 minutes, then let rest for a few before serving.
