  • 1 tablespoon (15 ml) soy sauce (low-sodium preferred)
  • 1 tablespoon (15 ml) cornstarch
  • 1 teaspoon (5 ml) sesame oil
  • 1/2 teaspoon (2.5 ml) ground ginger
  • 1/4 teaspoon (1.25 ml) black pepper
  • 1 tablespoon (15 ml) vegetable oil (e.g., canola, peanut, or sunflower)
  • 1 onion, thinly sliced
  • 1 red bell pepper, thinly sliced
  • 1 green bell pepper, thinly sliced
  • 1 cup (approximately 115g) broccoli florets
  • 1 cup (approximately 85g) snap peas, trimmed
  • 2 cloves garlic, minced
  • 1 inch (2.5 cm) piece of ginger, peeled and minced
  • 1/4 cup (60 ml) soy sauce (low-sodium preferred)
  • 2 tablespoons (30 ml) brown sugar
  • 1 tablespoon (15 ml) rice vinegar
  • 1 tablespoon (15 ml) sesame oil

  • 1/4 cup (60 ml) water
  • Sesame seeds (optional)

Instructions:

  1. Marinate the Beef: Combine beef with marinade ingredients in a bowl. Toss to coat and set aside while you prepare the vegetables.
  2. Prepare the Sauce: Whisk together all sauce ingredients in a small bowl until smooth. Set aside.
  3. Stir-Fry the Vegetables: Heat vegetable oil in a wok or large skillet over high heat. Add onion, bell peppers, and broccoli. Stir-fry for 3-4 minutes, until slightly tender-crisp. Add snap peas, garlic, and ginger. Stir-fry for another minute until fragrant.
  4. Cook the Beef: Push vegetables to one side of the wok. Add marinated beef to the empty side. Stir-fry until browned and cooked through, about 2-3 minutes. Be careful not to overcrowd the pan. If necessary, cook the beef in batches. Internal temperature of 145F (63C) for medium rare is recommended, with higher temps for greater doneness.
  5. Combine and Simmer: Pour the sauce over the beef and vegetables. Stir to combine and bring to a simmer. Cook until the sauce has thickened, about 1-2 minutes.
  6. Serve: Remove from heat and garnish with sesame seeds and green onions, if desired. Serve immediately over rice or noodles.
