Remove the melted cheese toasts from the broiler and slide onto a plate. Using a spatula, place the egg, sunny-side up, on a slice of cheesy toast. Top with bacon or ham, if desired, then top with the other cheese toast, cheese side down. Eat immediately, employing the hot sauce as desired, or return the sandwich to the skillet, adding more oil or butter if needed, and cook it as you would a grilled cheese sandwich until the bread is golden and crunchy, flipping the sandwich once. Then eat immediately.
