It's one of omelet types, Spanish one.
You need three eggs, tomatoes, onion, green peppers, yellow cheese and mushrooms.
You break the eggs in half hot stove,in a pan, after you have prepared the rest of ingredients. Thus you cut tomatoes in small pieces, peppers also, the yellow cheese. Before adding these ingredients, you have first fried the mushrooms, in low temperature then, you put the eggs, and later the rest of ingredients. You mix well and add the salt. Till it's done then you remove from stove. —Katerina Katapodi
