Heat the vegetable oil in a large skillet or wok over medium-high heat.

Add the cooked rice and stir-fry for a few minutes until heated through.

Push the rice to one side and crack the eggs into the pan. Scramble the eggs until fully cooked, then mix with the rice.

Add the mixed vegetables and green onions, stir-frying until the vegetables are tender.

Pour in the soy sauce and season with garlic salt or MSG, salt, and pepper.

Mix everything together well and serve hot.
