Saute the onion and garlic with the sesame seed oil in a large skillet or wok over medium-high heat for about two minutes. Add the frozen veggies and cook until tender, about 3-4 minutes.
Slide the veggies over one side of the skillet or wok, and pour the beaten eggs on the other side. Scramble the eggs until cooked but soft, and mix with the veggies.
Add the leftover rice and soy sauce, and mix well with the eggs and veggies until the rice is heated through. Serve hot.
Notes
To make fried rice the authentic way, the wok or skillet has to be very hot before adding the oil, and the oil very hot before you start cooking.
Scramble the eggs away from the veggies. It will not taste the same if you scramble the eggs with the veggies. Mix them after you scramble the eggs.
Freshly made rice doesn’t work as good as cold leftover rice.
