Ingredients:

  • 1 pound (450g) beef sirloin or flank steak, thinly sliced against the grain
  • 1 tablespoon soy sauce (low sodium preferred)
  • 1 tablespoon cornstarch (cornflour)
  • 1 tablespoon vegetable oil
  • 1/2 teaspoon ground black pepper
  • 2 tablespoons vegetable oil
  • 2 cloves garlic, minced
  • 1 inch ginger, peeled and minced
  • 1 red bell pepper, thinly sliced
  • 1 green bell pepper, thinly sliced
  • 1 cup broccoli florets
  • 1 cup snow peas (mangetout)
  • 2 green onions (scallions), chopped
  • 1/4 cup (60ml) soy sauce (low sodium preferred)
  • 2 tablespoons brown sugar (or honey)
  • 1 tablespoon rice vinegar
  • 1 tablespoon oyster sauce (optional)
  • 1 teaspoon sesame oil
  • 1 teaspoon cornstarch (cornflour)
  • 1/4 cup (60ml) water

Instructions:

  1. Slice beef thinly against the grain. Marinate beef in soy sauce, cornstarch, vegetable oil, and pepper for at least 15 minutes.
  2. Whisk together soy sauce, brown sugar, rice vinegar, oyster sauce (if using), sesame oil, cornstarch, and water in a small bowl. Set aside.
  3. Heat 1 tablespoon of vegetable oil in a wok or large skillet over high heat. Add garlic and ginger and stir-fry until fragrant (about 30 seconds).
  4. Add the marinated beef to the wok and stir-fry until browned and cooked through (about 2-3 minutes). Remove beef from the wok and set aside.
  5. Add the remaining 1 tablespoon of vegetable oil to the wok. Add bell peppers, broccoli, and snow peas and stir-fry until tender-crisp (about 3-4 minutes).
  6. Return the beef to the wok. Pour in the sauce and bring to a simmer, stirring constantly, until the sauce thickens (about 1-2 minutes).
  7. Garnish with chopped green onions and serve immediately over rice or noodles.
