In a large skillet or wok, heat 1 tablespoon of vegetable oil over medium-high heat. Add the diced chicken and season with salt and pepper. Stir-fry until golden brown and cooked through, about 5-7 minutes. Remove from the skillet and set aside.
In the same skillet, add the remaining tablespoon of vegetable oil and sesame oil. Add minced garlic and sauté for about 30 seconds until fragrant. Then, add the mixed vegetables and stir-fry for 3-4 minutes until they are tender.
Push the vegetables to one side of the skillet and pour the beaten eggs into the empty space. Scramble the eggs until cooked, then mix with the vegetables.
Add the cooked jasmine rice to the skillet, breaking apart any clumps. Combine everything together well.
Pour the soy sauce over the rice mixture and add the previously cooked chicken back into the skillet. Stir-fry everything together for another 2-3 minutes, until heated through and well combined.
Stir in the sliced green onions and toss everything one more time. Adjust seasoning with additional salt and pepper if necessary.
Remove from heat and transfer the fried rice to a serving platter. Optionally, sprinkle sesame seeds on top for garnish.
Notes
Using day-old rice helps achieve the best texture.
