Ingredients
- 1 pound (450g) flank steak, thinly sliced
- 1 red bell pepper, sliced
- 1 green bell pepper, sliced
- 1 yellow bell pepper, sliced
- 1 large onion, sliced
- 3 cloves garlic, minced
- 2 tablespoons soy sauce
- 1 tablespoon oyster sauce
- 1 tablespoon cornstarch
- 1 tablespoon vegetable oil
- 1 teaspoon sesame oil
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt
- 1/4 cup beef broth or water

Instructions
Step 1: Prepare the Beef
- Marinate the Beef: In a bowl, mix the sliced flank steak with soy sauce, oyster sauce, cornstarch, black pepper, and sesame oil. Let it marinate for at least 15 minutes to absorb the flavors.
Step 2: Prepare the Vegetables
- Slice the Vegetables: While the beef is marinating, slice the bell peppers and onion. Mince the garlic.
Step 3: Cook the Beef
- Heat the Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat.
- Stir-fry the Beef: Add the marinated beef and stir-fry until it’s browned and cooked through, about 5-7 minutes. Remove the beef from the skillet and set aside.
Step 4: Cook the Vegetables
- Sauté the Garlic and Onion: In the same skillet, add a little more oil if needed, and sauté the minced garlic and sliced onion until fragrant and the onion is translucent.
- Add Bell Peppers: Add the sliced bell peppers and stir-fry for about 3-4 minutes until they are slightly tender but still crisp.
Step 5: Combine and Serve
- Combine the Beef and Vegetables: Return the cooked beef to the skillet, add the beef broth or water, and stir everything together. Cook for another 2-3 minutes until the sauce thickens slightly.
- Adjust Seasoning: Taste and adjust the seasoning with salt and more black pepper if needed.
Final Presentation
- Serve: Serve the Pepper Steak hot over steamed rice or noodles. Garnish with sliced green onions or sesame seeds if desired.
