2 cups chopped cooked chicken
1/2 cup chopped celery
1/4 cup chopped onion
1 (12-ounce) package frozen vegetable combination (broccoli, carrot and water chestnuts), thawed
2 (10 3/4-ounce) cans condensed cream of chicken soup
1/4 teaspoon pepper
1/2 cup shredded Cheddar cheese
1 cup milk
1 cup all-purpose flour
1/4 teaspoon salt
Heat oven to 425°F.
Combine all filling ingredients except cheese in 12-inch skillet. Cook over medium-high heat, stirring occasionally, 10-14 minutes or until mixture comes to a boil.
Combine milk, eggs and butter in bowl; beat at medium speed 1 minute. Add flour and salt; continue beating until smooth.
Pour hot chicken mixture into ungreased 13x9-inch (3-quart) baking dish. Top with cheese. Pour topping mixture carefully over cheese. Bake 25-30 minutes or until puffed and lightly browned. Serve immediately.
Pot pies are usually topped with a pastry crust. The batter used for the "crust" of this pot pie is more typically used for popovers, baked in special individual popover pans. When heated, the thin batter creates enough steam to cause the batter to "pop up" and form a puffed topping.
