Cheese Omelet

1. Combine all ingredients except butter and sour cream in a bowl and beat with a wire whisk or mixer until smooth. 2. Melt butter in a large non-stick omelet pan. 3. Add content from bowl and cook over low flame until eggs begin to set. 4. Loosen eggs from side with spatula. Tilt pan again to allow uncooked eggs to run to the sides. 5. Carefully fold outer edges of omelet into the center to resemble a flat cone. If you want them to puff, turn off heat and put a lid on for about 1 minute. 6. Slide out of pan and serve plain or garnish with the sour cream (optional). 7. Source: adapted from Dr Atkins' New Diet Cookbook.
