I was a bit vague....
I use at least double egg whites to yolks...just don't like the taste of yolks.
A bit of extra moisture (about 1-2 TBL of water, milk or cream) helps the steaming/fluffy part.
Cook over low heat. Stirring gently, remove from heat as eggs start to lump up. There should be visible moisture yet.
Add cheese of choice...even cottage cheese is good, parma, Tillamook, goat, chive cream cheese..
Cover with a lid and set off the heat for a few minutes.
If you didn't add cheese, this is a good point to add a bit of butter--following in the footsteps of James Beard.
Season well.
