Cut the tomatoes into bite-sized pieces and slice the green onion as desired.

Crack the eggs into a bowl, add 0.5 tsp of salt, and whisk until well combined.

Heat a pan over medium heat, add enough cooking oil, and pour in the whisked eggs. Stir gently as the bottom sets to avoid forming large chunks.

Transfer the cooked eggs to a separate bowl and set aside.

In the same pan, add more cooking oil and stir-fry the green onion until fragrant.

Add the tomatoes to the pan along with soy sauce, oyster sauce, and black pepper. Stir-fry until the tomatoes are softened.

Return the cooked eggs to the pan and mix well with the tomatoes. Stir-fry briefly to combine.
