I used a deep dish Pie Tin, or use a 9X12X2 inch casserole dish. This is the size pie tin I used. Leave pie crust out of box on counter for about 15 minutes to reach room temperature so it unrolls easily.
Line bottom of pan with one of The full unrolled pie crust. It covers the entire bottom of the pie tin.PREHEAT OVEN TO 400 DEGREES F.
Drain canned Chicken breast and add to pie dish.
Add the frozen peas & carrots to a medium size bowl and heat in microwave for 5 minutes to remove ice crystals, drain any excess liquid.
Sprinkle most of peas over top of chicken, and save the remainder to the left over dumplings.
Sprinkle lemon pepper and thyme over vegetables and chicken in pan.
Add the left over chicken & dumplings to a large bowl then add the minced onions, and stir to mix with the remaining peas & carrots. The link for my VEGETABLE CHICKEN & DUMPLINGS recipe posted here is Vegetable Chicken & Dumplings
Ladle mixture into pie dish.
Unroll remaining pie crust and cut into medium size strips.
Use a fluted pastry wheel, pizza wheel or knife, to make desired size strips
Arrange strips over pot pie in desired pattern, overlapping and interlocking as you go if desired.
Crack a large egg into a small bowl, add 1 tablespoon of water and beat with fork till blended.
Brush top of crust generously with egg wash using a pastry brush.
Combine about 1 1/2 teaspoon coarse black pepper & 1 teaspoon kosher salt together in a small bowl and sprinkle over the top of crust for added crunch and flavor.
Place in preheated 400 degrees F oven, & bake for 45 minutes to an hour, or until crust is golden brown and mixture is hot & bubbly. BE SURE TO USE A SHALLOW PAN TO CATCH ANY POTENTIAL DRIPS FROM THE PIE AS IT COOKS. EITHER PLACE PIE IN THE PAN BEFORE COOKING OR BENEATH THE PIE AS IT COOKS.
Sprinkle top with chopped chive if desired and serve while still hot.
I made one to give away, using Pillsbury Crescent Rolls because I was out of Pie Crust, and it turned out FANTASTIC. THIS IS THE ONE I GAVE AWAY, to my house keeper, had planned to save it in the freezer for an easy dinner idea the next time. They LOVED IT.
