Hard-Boiled Egg Casserole

Melt butter or margarine in a saucepan over low heat.

Add onion and cook until tender. Combine flour and milk with butter and onion, stirring constantly, until thickened. Add cheese until melted.

Layer half of the eggs in a 10 x 6 x 1 1/2-inch dish. Pour half the onion and cheese mixture over the eggs.

Sprinkle half of the potato chips and half of the bacon over the mixture. Repeat this process with the remaining ingredients.

Bake at 350° for 25 minutes.
