Ingredients:
• 300g beef (thinly sliced)
• 1 medium onion (sliced)
• 1 red bell pepper (sliced)
• 1 green bell pepper (sliced)
• 2-3 fresh green chilies (optional, sliced)
• 3 cloves garlic (minced)
• 2 tbsp soy sauce
• 1 tbsp oyster sauce
• 1 tbsp cornstarch (for coating the beef)
• 1 tsp sugar
• 1 tsp black pepper
• 1 tbsp vegetable oil
• 1/4 cup water or beef broth
• Spring onions (optional, chopped for garnish)
Instructions:
1. Prepare the Beef:
• Mix the sliced beef with a pinch of salt, black pepper, and cornstarch. Let it marinate for 10 minutes.
2. Stir-fry the Beef:
• Heat the vegetable oil in a pan or wok over medium-high heat.
• Add the marinated beef and stir-fry for 2-3 minutes until it is browned but still tender. Remove and set aside.
3. Cook the Vegetables:
• In the same pan, add the garlic and sauté for a few seconds until fragrant.
• Add the onions, bell peppers, and green chilies. Stir-fry for 2-3 minutes until slightly softened.
4. Combine Everything:
• Return the beef to the pan, and add soy sauce, oyster sauce, sugar, and a bit of water or beef broth.
• Stir-fry everything together for another 2 minutes until the sauce thickens slightly and coats the beef and vegetables well.
