Cut cabbage in chunks. Boil in salted water until
wilted. Add onions. In saucepan melt butter till bubbling. Add flour and
cook without burning till blended together to make a rue. Add milk a
little at a time, stirring until thickened. Add salt and pepper. Mix
white sauce and cabbage. Add to greased baking dish. Sprinkle top with
buttery toasted bread crumbs. I make my own by grating bread and melting
butter in frying pan, add crumbs and toast slightly.
Bake at 350 for about 30 minutes or until bubbly.
