Preparing Chinese Beef and Broccoli is simple. Just follow these steps for a successful dish:

1. Marinate the Beef: In a bowl, combine the soy sauce, oyster sauce, and cornstarch. Add the sliced beef and mix well to coat. Let it marinate for about 10 minutes.

2. Prepare the Broccoli: While the beef is marinating, bring a pot of water to a boil. Add the broccoli florets and blanch for about 2 minutes until vibrant green. Drain and set aside.

3. Cook the Beef: Heat a tablespoon of oil in a large skillet or wok over medium-high heat. Add the marinated beef in a single layer. Cook for about 2-3 minutes until browned and just cooked through. Remove from the skillet and set aside.

4. Sauté Aromatics: In the same skillet, add a little more oil if necessary. Sauté the minced garlic and ginger for about 30 seconds until fragrant.

5. Combine Ingredients: Return the cooked beef to the pan and add the blanched broccoli. Stir everything together, tossing to coat the vegetables and beef with the garlic and ginger.

6. Finish Cooking: Stir-fry for an additional 2-3 minutes until all ingredients are heated through, and everything is coated in the sauce.

7. Serve Immediately: Remove from heat and serve your Chinese Beef and Broccoli hot with steamed rice or noodles.
