In a skillet, saute the onion and celery until tender in 1 tablespoon butter.

Gently stir in the diced chicken, potatoes, carrots, peas and corn.
4 cups diced cooked chicken, 4 to 6 large carrots, 3 cups potatoes, 2 cups petite frozen peas, 2-3 cans corn kernels

2 boxes pre-made refrigerate pie crust
Divide the filling between two pie plates. Add thin slices of butter on top of filling. Add the top crust and seal, flute edges and decorate as desired.
In a small bowl, beat together the egg and 1 tablespoon water. Brush the mixture over the top of the pies. Cover edges of pie crust with foil and bake at 400-degrees F for 15 minutes. Then turn down the heat to 375-degrees and bake for about 25 minutes. Remove the foil laround the edges and bake for 5-10 minutes longer until the crust is golden brown.
