Omelette in Thailand is one of the most popular dishes, it is prepared with a variety of fillings, with meat, vegetables, legumes, etc., but it necessarily includes fish sauce. Another feature of the Thai omelette is that it does not suit olive oil or vegetable oil, they do not give enough flavour. If you see "kai yat sai" in the Thai restaurant menu, be sure to try - this is the Thai omelette.
