This is a wonderful way to use hard boiled eggs you might have left over.
6 hard boiled eggs, sliced
1/2 stick of butter
2 cups of milk
4 tablespoons of flour
Melt the butter in a frying pan. Stir in the flour, then the milk. Cook over medium heat stirring constantly until sauce thickens. Gently fold in egg slices. Serve on buttered toast.
