Ingredients:
- 1 lb (450g) beef sirloin or flank steak (thinly sliced against the grain)
- 2 tbsp vegetable oil (or another cooking oil)
- 1 large onion (sliced)
- 1 red bell pepper (sliced)
- 1 green bell pepper (sliced)
- 1/4 cup soy sauce
- 1/4 cup teriyaki sauce
- 2 tbsp brown sugar or honey
- 2 garlic cloves (minced)
- 1 tsp fresh ginger (grated, or 1/2 tsp ground ginger)
- 1 tbsp cornstarch mixed with 2 tbsp water (optional, for thickening)
- Cooked rice or noodles (for serving)
- Sliced green onions and sesame seeds (for garnish, optional)
Instructions:
1. Prepare the Beef:
- In a bowl, combine the sliced beef with 1 tbsp of soy sauce and let it marinate for about 10-15 minutes. This helps tenderize the meat and adds flavor.
2. Cook the Beef:
- Heat 1 tbsp of vegetable oil in a large skillet or wok over high heat.
- Add the beef in a single layer and cook for 2-3 minutes per side, or until it is browned but not fully cooked through. Remove the beef from the skillet and set aside.
3. Sauté the Vegetables:
- In the same skillet, add another tablespoon of oil if needed.
- Add the sliced onion and bell peppers. Cook for 4-5 minutes, stirring occasionally, until the vegetables are tender-crisp.
4. Add Garlic and Ginger:
- Add the minced garlic and grated ginger to the vegetables. Cook for another minute, until fragrant.
5. Combine Ingredients:
- Return the beef to the skillet with the vegetables.
- In a small bowl, mix together the soy sauce, teriyaki sauce, and brown sugar or honey.
- Pour the sauce mixture over the beef and vegetables.
6. Simmer and Thicken:
- Stir to coat the beef and vegetables with the sauce.
- Let it simmer for 3-5 minutes, or until the beef is cooked through and the sauce has thickened slightly. If you want a thicker sauce, stir in the cornstarch mixture and cook for another minute or until the sauce reaches your desired consistency.
7. Serve:
- Serve the beef and vegetables over cooked rice or noodles.
- Garnish with sliced green onions and sesame seeds if desired.
