Follow these steps to make your delicious Steak and Shrimp Stir Fry:

1. Marinate the Steak: In a bowl, combine the sliced steak, soy sauce, oyster sauce, and cornstarch. Let it marinate for at least 10 minutes.
2. Prepare the Shrimp: While the steak is marinating, season the shrimp with salt and pepper. Set aside.
3. Heat the Oil: In a large skillet or wok, heat 1 tablespoon of vegetable oil over medium-high heat.
4. Cook the Steak: Once the oil is hot, add the marinated steak. Stir-fry for about 3-4 minutes until the steak is browned and cooked to your liking. Remove from the pan and set aside.
5. Cook the Shrimp: In the same pan, add another tablespoon of oil if needed and toss in the shrimp. Cook for 2-3 minutes until they turn pink and opaque. Remove and set aside.
6. Stir Fry Vegetables: Add the broccoli, bell pepper, and carrot to the pan. Stir-fry for about 3-4 minutes until the vegetables are tender but still crisp.
7. Add Aromatics: Stir in the minced garlic and grated ginger. Cook for an additional minute until fragrant.
8. Combine: Return both the steak and shrimp to the pan. Toss everything together and cook for another 1-2 minutes to heat through.
9. Serve Immediately: Remove from heat and serve hot over cooked rice or noodles.
