Put the butter or bacon grease in a heavy bottom pan and preheat it on the lowest heat.
While the pan is heating, crack and beat 5 eggs.
After the pan is hot, pour the beaten eggs into the pan.
Add the cheese.
Continually stir as the eggs cook. Use your spoon to break up and stir in the cheese.
When the eggs have thickened and cooked, remove from the pan and serve.
