Instructions

  1. Step 1: In a medium bowl, toss 12 oz thinly sliced flank steak with 3 tbsp soy sauce and 1 tbsp cornstarch until beef is evenly coated. Let marinate for 10 minutes.
  2. Step 2: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add the beef in a single layer and stir-fry for 2-3 minutes until browned but still tender. Remove beef from pan and set aside.
  3. Step 3: In the same pan, add 5 minced garlic cloves and sauté for 30 seconds until fragrant. Add 1 large sliced red bell pepper and 1 large sliced green bell pepper, stir-frying for 3-4 minutes until crisp-tender.
  4. Step 4: Return the beef to the pan along with 2 sliced scallions, 1 tsp sesame oil, 1 tsp brown sugar, and freshly ground black pepper to taste. Stir-fry everything together for 1-2 minutes until heated through and the sauce coats the beef and vegetables.
  5. Step 5: Remove from heat and serve immediately over steamed rice or noodles.
