Wash the tomatoes and green onion thoroughly. Dice the tomatoes and finely slice the green onion.
Beat the eggs in a bowl, add a pinch of salt, and mix well.
Add cooking oil to a pan, pour in the egg mixture, and gently scramble until cooked. Remove and set aside.
In the same pan, add some oil and sauté the green onion until fragrant.
Add the tomatoes, then season with a little salt and sugar. Stir-fry together.
Return the cooked eggs to the pan and stir-fry with the tomatoes until well combined.
Transfer to a plate and serve.
