My omelets never look good. Use your own technique to get it into omelet shape. What I have to add to the plan is a suggestion for fluffing your eggs. Put them in the blender. Whir them around with a bit of rice milk or a splash of oil, both add a bit of fat just like milk to make your eggs a little richer.
If you're me you then saute the spinach to get it defrosted, pour the egg over it in the frying pan and flip it when it smells overcooked. I'm not proud of this technique but I'm not an egg lover.
