Heat the butter in a skillet over moderate heat and saute the bell pepper, scallions, and mushrooms until tender but not brown, about 5 minutes.
Add the eggs, salt, and pepper and cook, stirring frequently, until the eggs are set.
Transfer the egg mixture to the bottom halves of the bread, add the crumbled bacon, and top with the remaining bread.
Sit back and enjoy any time of the day.
