Spray your egg pan and then crack the eggs in the pan (I don't really pre-whisk the eggs for this, you can if you want). Break up the eggs with your wooden spoon and then add your American cheese in bits and pieces. Now turn on your heat to a medium high or low heat, and gradually stir the eggs until bits of it start to cook. As the eggs cook, be careful not to overcook your eggs.
I like my scrambled eggs slightly runny. I think this is the best way to eat these. If you truly hate White American Cheese, you don't have to use it, but I think it actually melts perfectly and gives the sandwich a great cheesy flavor.
Now butter your bread on the outside of the sandwich, then place the sandwich on the egg pan and brown each side. Press down with a spatula onto the sandwich you make sort of like a egg panini sandwich.
Cut in half and enjoy!
