Creating Ginger Apple Beef Stir-Fry is straightforward. Follow these steps:

1. Prepare the Beef: If not pre-sliced, thinly slice the beef against the grain. This ensures tenderness.

2. Marinate: In a bowl, mix the sliced beef with soy sauce, oyster sauce, salt, and pepper. Let it marinate for at least 10 minutes for enhanced flavor.

3. Heat the Pan: In a large skillet or wok, heat the vegetable oil over medium-high heat until hot.

4. Cook the Beef: Add the marinated beef to the pan in a single layer. Cook for about 3-4 minutes, or until browned. Stir frequently to ensure even cooking. Remove the beef from the pan and set aside.

5. Sauté Vegetables: In the same pan, add more oil if needed. Add the garlic and ginger, sautéing for about 30 seconds until fragrant. Add the sliced apples, bell pepper, and carrot. Stir-fry for 3-4 minutes until slightly softened but still crisp.

6. Combine Ingredients: Return the cooked beef to the pan with the apples and veggies. Toss everything together to combine well.

7. Final Touches: Taste and adjust seasoning if necessary. Cook for an additional 1-2 minutes until everything is heated through.

8. Serve: Remove from heat. Garnish with chopped green onions and sesame seeds before serving.

Following these steps will make your Ginger Apple Beef Stir-Fry not only easy to prepare but also deliciously satisfying!
