Slice the beef thinly and marinate with soy sauce, a touch of sesame oil, and minced garlic. Cook your rice a day in advance and store it in the fridge to ensure it’s firm and ready for stir-frying. Whisk the eggs in a small bowl.
Heat a large skillet or wok over medium-high heat with a bit of oil. Sear the beef until browned, then remove it from the pan and set aside.
Add the whisked eggs to the pan and scramble them lightly, then remove and set aside.
Add a splash of oil and stir-fry the frozen veggies until tender and fragrant.
Add the rice to the pan, breaking up any clumps, and stir-fry until heated through. Return the beef and eggs to the pan, then season with soy sauce and sesame oil. Mix everything thoroughly.
Sprinkle chopped green onions on top for a fresh finish and serve hot!
