I did try a Dukan omelette this morning.
First, I whisked 2 eggs (yolk limit for a day) with 2 egg whites and a splash of skim milk with a fork for about 15 seconds. Then I poured it into a warmed nonstick frypan on medium heat. I use my fork to move the mix around and let the unset mix fill the gaps. When about 50% set I added some Huon smoked salmon and a few teaspoons of Philadelphia extra light to the top of one half of the omelette and ground some black pepper. When about 95% set it was time to fold in half and transfer to a plate.
