Helen's Eggs In Casserole

This is another one of Helen's more odd recipes.

Helen's Eggs In Casserole

Hard boiled eggs (allow 2 per person)
Cream Sauce**
Salt and Pepper, to taste
Diced Celery, as much as you want for flavor
1 tsp. minced onion
1 cup buttered bread crumbs

Quarter half eggs and place carefully in casserole. Pour over half cream sauce. Sprinkle celery and onion over sauce. Repeat; then cover with crumbs. Bake uncovered 20 minutes.*
Variations: To above add crab meat, tuna fish, or mushrooms.
May be prepared ahead; place in refrigerator. If chilled, allow 10 minutes more for baking.
*Helen never specified how hot of an oven so bake at 350 degrees.
**Helen never specified whether this was a thin, medium, or heavy cream sauce. The recipe is most likely a basic medium cream sauce listed below.

Basic Medium Cream Sauce

2 Tbls. butter
2 Tbls. flour
1 cup milk

Melt butter in a 2 quart sauce pan. Stir in flour and allow to cook for 1-2 minutes, stirring constantly. Add milk and stir until thickened. If you want a thin sauce then only use 1 Tbls. each of the flour and butter. For a thick sauce use Tbls. each of butter and flour.
