What condiments do you add to your breakfast sandwiches?

Plain bagel, 2 eggs, 2 slices of American Cheese.

Usually I mix some Kewpee mayo with Franks wing sauce. But I also usually use smoked Gouda or smoked Gruyère... I was out of both, so I grabbed the American slices and skipped condiments. It lacked flavor, however.
