In a big bowl, mix eggs with milk, cheese, tomatoes, onion, salt and pepper
In a pan, add 1 tbs oil and saute the garlic with the spinach for about a minute
Add the spinach to the big bowl and mix it properly
In a flat pan, add little oil and spread the mix from the bowl.
Low the heat and let it cook slowly. If you want you can flip it and cook the other side too.
Add few drops of Tabasco sauce on your omlette and eat it hot with some bread toast :)
