Ingredients

Instructions

  1. Step 1: In a small bowl, whisk together 1/4 cup soy sauce, 2 tbsp sesame oil, 1 tbsp minced fresh ginger, 3 minced garlic cloves, 1 tbsp brown sugar, and 2 tbsp water. Set sauce aside.
  2. Step 2: Toss 1 lb thinly sliced flank steak with 1 tbsp cornstarch until evenly coated.
  3. Step 3: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add the steak in a single layer and sear for 2-3 minutes without stirring until browned on one side.
  4. Step 4: Stir-fry the steak for another 2 minutes until mostly cooked through. Remove steak from pan and set aside.
  5. Step 5: In the same pan, add sliced 1 large red bell pepper and 1 large yellow bell pepper. Stir-fry for 3-4 minutes until just tender-crisp.
  6. Step 6: Return steak to the pan. Pour the prepared sauce over the beef and peppers, tossing everything together. Cook for another 2 minutes until sauce thickens and coats all ingredients.
  7. Step 7: Remove from heat and garnish with 3 sliced green onions. Serve immediately over steamed rice or noodles.
