Creating Chinese Beef and Broccoli is straightforward if you follow these simple steps:

1. Marinate the Beef: In a bowl, combine the sliced flank steak with 1 tablespoon of soy sauce, cornstarch, and a pinch of salt. Let it marinate for about 10 minutes.
2. Blanch the Broccoli: Bring a pot of water to a boil. Add the broccoli florets and blanch for 2-3 minutes. Drain and set aside.
3. Prepare the Sauce: In a small bowl, mix together the remaining soy sauce, oyster sauce, beef broth, and sesame oil. Set aside.
4. Cook the Beef: Heat a large pan or wok over medium-high heat. Add the vegetable oil and swirl to coat. Add the marinated beef and stir-fry for about 3-4 minutes until browned. Remove from the pan and set aside.
5. Sauté Aromatics: In the same pan, add the minced garlic and ginger. Stir-fry for about 30 seconds until fragrant.
6. Combine Ingredients: Return the beef to the pan, add the blanched broccoli, and pour in the sauce. Stir well to coat everything evenly.
7. Thicken Sauce: Cook for an additional 2-3 minutes, allowing the sauce to thicken slightly and coat the beef and broccoli.
8. Season: Taste and adjust seasoning with salt and pepper if needed.
9. Serve: Remove from heat and serve immediately over cooked rice or noodles.
