Ingredients

• 500 grams beef sirloin or flank steak
• 1 medium red bell pepper
• 1 medium green bell pepper
• 1 medium yellow bell pepper
• 3 tablespoons soy sauce (low sodium)
• 2 tablespoons oyster sauce
• 1 tablespoon sesame oil
• 1 teaspoon cornstarch
• 3 cloves garlic cloves, minced
• 1 teaspoon ginger, minced or grated
• 2 tablespoons vegetable oil
• 2 stalks green onions, sliced
• 0.5 teaspoon red chili flakes (optional, for heat)
• 0.5 teaspoon salt
• 0.5 teaspoon black pepper

Directions

Step 1

Prepare the beef by slicing it thinly against the grain into bite-sized strips. Set aside.

Step 2

In a small bowl, prepare the marinade by combining soy sauce, oyster sauce, sesame oil, cornstarch, salt, and black pepper. Mix well.

Step 3

Add the beef strips to the marinade and mix until evenly coated. Let marinate for 15 minutes.

Step 4

While the beef is marinating, wash and thinly slice the red, green, and yellow bell peppers into strips. Mince the garlic and ginger and set aside.

Step 5

Heat 1 tablespoon of vegetable oil in a large wok or skillet over medium-high heat. Once hot, add the marinated beef in a single layer and cook for 2-3 minutes until browned but not fully cooked. Remove the beef from the wok and set it aside.

Step 6

Add the remaining 1 tablespoon of vegetable oil to the wok. Stir in the minced garlic and ginger, and cook for 30 seconds until fragrant.

Step 7

Toss in the sliced bell peppers and stir-fry for 3-4 minutes until they are slightly softened but still crisp.

Step 8

Return the partially cooked beef to the wok and stir-fry with the bell peppers for another 2-3 minutes until the beef is fully cooked and everything is well combined.

Step 9

If desired, sprinkle red chili flakes for heat and mix well.

Step 10

Remove from heat, garnish with sliced green onions, and serve immediately. This dish pairs well with steamed rice or a side of quinoa for an extra boost of protein.
