Set 8 pieces of bread into a 9″ x 13″ (23 x 33 cm) buttered, glass baking dish.
Cover bread with slices of turkey. Lay slices of cheese on top, spread spinach over the cheese and then cover with remaining slices of bread to make it like a sandwich.
In a bowl, whisk eggs, egg whites and pepper. To the egg mixture add dry mustard, onion, Worcestershire sauce, milk and Tabasco or hot sauce.
Pour over the sandwiches, cover and let stand in fridge overnight. In morning, melt butter, pour over top. Cover with bran cereal.
Bake, uncovered, 1 hour at 350 deg.F (180 deg.C). Let sit 10 minutes before serving. Serve this with fresh fruit.
