Instructions

1. In a bowl, mix the soy sauce, oyster sauce, cornstarch, minced garlic, and minced ginger to create a marinade.
2. Add the sliced beef to the marinade, ensuring all pieces are well coated. Let it marinate for about 10 minutes.
3. While the beef is marinating, blanch the broccoli in boiling water for 2 minutes, then transfer to an ice bath to stop the cooking process. Drain and set aside.
4. Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat.
5. Add the marinated beef to the skillet and stir-fry for about 3-4 minutes, until browned and cooked through. Remove the beef from the skillet and set aside.
6. In the same skillet, add the remaining tablespoon of vegetable oil. Add the blanched broccoli and stir-fry for 2 minutes.
7. Return the beef to the skillet and pour in any remaining marinade. Stir well to combine and cook for an additional 2 minutes until the sauce thickens.
8. Drizzle with sesame oil, and season with salt and black pepper to taste.
9. Garnish with chopped green onions before serving.
