Ingredients

Instructions

  1. Step 1: Toss 12 oz thinly sliced flank steak with 1 tsp cornstarch and 1/4 tsp black pepper in a bowl until evenly coated.
  2. Step 2: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add the beef strips and stir-fry for 2-3 minutes until just browned but still tender. Remove beef and set aside.
  3. Step 3: In the same pan, add 4 minced garlic cloves and sauté for 30 seconds until fragrant. Add 1 large sliced red bell pepper and 1 large sliced yellow bell pepper, stir-frying for 3-4 minutes until peppers are slightly tender but still crisp.
  4. Step 4: Return the beef to the pan and add 3 tbsp soy sauce, 2 tbsp oyster sauce, and 1 tsp sesame oil. Stir-fry everything together for 1-2 minutes until the sauce thickens and coats the beef and peppers.
  5. Step 5: Remove from heat and garnish with 2 sliced green onions before serving immediately.
