Preheat oven to 350 degrees F. Lay crust into pie pan (remove refrigerated crusts from fridge about 30 minutes before making this to thaw a bit so it is easier to roll out). Roll out crust into sprayed pie pan and shape to cover bottom and covers the sides.
In a microwave pour frozen veggies into a bowl with a few tbsp of water, cover with a paper towel or plate. Heat for about 3 minutes stirring halfway thru or long enough to defrost and make them tender but still a bit al dente.
Dice leftover smoked chicken into bite size pieces and pour into a bowl. Dump in condensed soup with vegetables and a sprinkle of salt and pepper. Stir together. Pour filling into pie pan lined with pie crust. Spread out and then roll our 2nd, top, pie crust over the top. Pinch the outer edges closed all the way around.
Use a knife to make 4 slits on the top of the top crust. Whisk egg in a bowl and use a brush to brush an egg wash over the top of the whole thing with a sprinkle of salt and pepper on top.
Bake for 35-40 minutes or until the top is perfectly golden brown. Remove, set on a cooling rack and let sit for 15 minutes.
