Heat a large skillet or wok over medium-high heat. Add 1 tablespoon of vegetable oil and swirl to coat.
Pour in the beaten eggs and scramble until just set. Remove from the pan and set aside.
Add the remaining tablespoon of vegetable oil to the pan, followed by the minced garlic. Sauté until fragrant, about 30 seconds.
Toss in the mixed vegetables and stir-fry for 2–3 minutes, or until they begin to soften.
Increase the heat to high and add the cooked rice, breaking up any clumps with a spatula. Stir-fry for 3–4 minutes, ensuring the rice heats evenly.
Drizzle soy sauce and sesame oil over the rice, stirring to combine. Return the scrambled eggs and any cooked protein to the pan. Stir until everything is well mixed.
Garnish with sliced green onions and serve hot.
