In a bowl, toss the sliced beef with 1 tablespoon of soy sauce and cornstarch; marinate for 15 minutes.
Heat 1 tablespoon of vegetable oil in a wok or large skillet over high heat until shimmering.
Add the beef in a single layer and sear until browned, approximately 2-3 minutes; remove beef and set aside.
Add the remaining vegetable oil to the wok; stir-fry the ginger and garlic for 30 seconds.
Add the broccoli and carrots; stir-fry for 3 minutes until tender-crisp.
Push the vegetables to the sides of the wok; pour the eggs into the center and scramble until fully set.
Add the chilled rice and peas to the wok, breaking up any rice clumps with a spatula.
Incorporate the remaining soy sauce, oyster sauce, and sesame oil; toss to coat evenly.
Return the beef to the wok and stir-fry for an additional 1-2 minutes until thoroughly heated.
Garnish with sliced green onions before serving.
