In a large bowl whisk together the eggs, milk, dry mustard, salt and pepper, until smooth. Set aside.
Grease a 9 x 13 baking dish with butter (or spray it with cooking spray).
Add the chunks of bread to the baking dish.
Sprinkle on the ham, bacon, onions and green pepper.
Then sprinkle on the cheese.
Pour the milk/egg mixture over the ingredients in the baking dish.
Cover with tin foil and let rest overnight in the fridge.
In the morning, preheat your oven to 350 degrees F and put the casserole in the oven while the oven preheats.
Bake, uncovered, for 45 – 50 minutes (until the casserole is not jiggly). NOTE: If you notice the casserole is getting too dark, cover it with tin foil and resume baking.
Let sit for about 10 minutes before serving.
