In a wok or large skillet, heat the vegetable oil over medium-high heat. Add the beaten eggs and scramble them until lightly cooked. Set them aside on a plate.
In the same wok, add a drizzle of vegetable oil and sauté the minced garlic until fragrant.
Toss in the thinly sliced beef and stir-fry until it's cooked to perfection.
Introduce the mixed vegetables to the wok, and continue to stir-fry until they're tender-crisp.
Now, add the cooked rice to the wok, mixing it thoroughly with the other ingredients.
Pour in the soy sauce, oyster sauce, and sesame oil, evenly coating the entire mixture.
Season with ground black pepper and a pinch of salt, enhancing the flavors to your liking.
Reintroduce the scrambled eggs into the wok, gently folding them into the rice and meat ensemble.
Once all the ingredients have harmoniously combined, remove the wok from heat.
Garnish the Arroz Chaufa de Carne Peruano with finely chopped green onions, adding a touch of freshness and vibrancy.
