1. Preheat oven to 350° F.
2. Combine prepared Gravy, milk, chicken, vegetables, and seasoning in a multipurpose pot. Slowly heat to simmering, stirring regularly.
3. Add filling to a shallow 9” (23 cm) pan and cool to room temperature. Top with pie crust and brush with milk. Cut small slashes so steam can escape.
4. Bake 15–20 min, or until golden-brown and heated through. Cool for 5 min before serving.
