Yes I have. I ate the cutout bread so it would not be wasted. Then I had an egg with a crust. I decided that idea was not as good as it seemed at first.
Here is a better idea: crack the egg into a bowl and separate the yolk any way you know how. Fry the whites however you like them and add the yolk before the whites are done. This gives a much nicer egg. Serve the toast separately.
I first saw it done in the movie Moonstruck. The mother made it and it looked so good. Then I saw it again in the Meddler and she made it look a little easier so I thought I would try it and now I am hooked on it.
