Cover the omelette with a sheet of aluminium foil and leave to rest like this for a few minutes before serving to finish cooking gently.
Remarks
In Provence, tomato omelettes are often eaten cold. This is the meal eaten by the hunters of Bartavelles (Marcel's father and uncle Jules) in 'My Father's Glory' (La Gloire de Mon Père) by Marcel Pagnol.
And to drink?
My father used to say, "With an omelette, you need a drop of white!", and he was absolutely right, so I suggest a very dry white, such as a Muscadet.
