I find that frequent pauses with a quick stir works well. You learn your micowave and you can get the times down pretty good. Also it is key not to over cook. Near the end if they are just a little runny, a good stir with the heat already held by thge eggs will actually cook them a little more.
My Current process
1 egg + 1 Carton of whites + 1 Slice of NO fat swiss.
1 min/stir , 1 min/stir, 1 min/stir, 20 sec/stir. Serve with a sprinkle of peper and some ANBP on the side. MMMMmmmmmmmm
and I second the PAM.
