Chicken Cordon Bleu Casserole

Cook and shred 3 chicken breast-halves.  Don't overcook them, as they will be dry as they continue to cook some more when heating with the entire casserole later.
Dice 1/2 lb. ham
1/4 lb. Swiss cheese, grated or sliced thinly

Spray smaller baking dish with non-stick spray.  Preheat oven to 350 degrees.  Spread shredded chicken in bottom of baking dish.  Scatter diced ham over top of chicken.  Spread the Swiss cheese on top of the ham.

For the sauce:
4 Tbl. butter
4 Tbl. flour
2 cups whole milk
1 Tbl. lemon juice
1/4 tsp. salt
1/8 tsp. paprika
Melt butter in saucepan and whisk in flour to make a roux.  Slowly add milk and other ingredients, whisking to make a gravy.  Pour sauce evenly over the casserole.

For topping:
1-1/2 cups bread crumbs
3 Tbl. melted butter
1/2 tsp. dried parsley
Add melted butter to bread crumbs and parsley.  Toss together.  Sprinkle over the top of the casserole.
Bake casserole for about 30 min until hot and bubbly and crumbs are golden brown.  Allow to cool and set for at least 20 min. before serving. (If you don't let it cool and set, there will be a liquid in the bottom of the dish when it's served.)
