How most recipes sound to me:
Put large tortilla in pan greased with olive oil. Turn on low heat. Add four eggs, beat the eggs. Ruin with diced white onion. Dice and add cherry tomatoes. Ruin further with chopped green onions.
Bake. Add cheese, bake some more at high temperature to brown the cheese.
Sprinkle with diced parsley, and to finish, ruin with chives.
