10 slices Hearty white bread, remove crusts and cut into cubes
11/2 c. Cheddar cheese, shredded
11/2 c. diced ham
2T. instant minced onion or flakes - sometimes I use fresh
11/2 tsp. salt
3 tsp. dry mustard
41/2 c. milk
Spray a 9 x 13-inch glass pan and a 7 x 12-inch glass pan with butter flavored spray and place the bread in the bottom of pans. Sprinkle diced ham & cheese on the bread. * Sprinkle instant onion over ham & cheese. In a medium bowl mix the eggs, salt, dry mustard, and milk. Pour the egg mixture over the casserole. Cover with plastic wrap and refrigerate overnight.
Bake in a 350° oven for about 45 - 50 minutes.
