A possible variation, tomato souflée omelette: pour half the mixture into pan, then add a layer of cooked tomato slices (pan-fried beforehand in a little olive oil), and finally add the remaining mix. Then cook and serve as usual.
Remarks
The ideal utensil for this recipe is a non-stick frying pan with removable handle.
Serve with a herb salad on the side, as I think that something with a hint of acidity makes a good accompaniement.
