Prepare the tomatoes and eggs, and cut them into suitable sizes.
Beat the eggs with a pinch of salt.
Add oil to a pan and stir-fry the eggs first; when they are halfway cooked, transfer them to a bowl.
Using the same pan, stir-fry the tomatoes until slightly cooked.
Put the eggs back into the pan and gently stir-fry together with the tomatoes.
Season with salt to taste.
