Instructions

  1. Step 1: Heat 1 tbsp sesame oil in a large wok or skillet over high heat until shimmering; add 12 oz thinly sliced flank steak and stir-fry for 2-3 minutes until browned but still tender; remove steak and set aside.
  2. Step 2: In the same wok, add remaining 1 tbsp sesame oil, 4 minced garlic cloves, and 1 tbsp grated ginger; stir-fry for 30 seconds until fragrant.
  3. Step 3: Add 1 medium julienned red bell pepper and 3 sliced green onions; cook for 2 minutes until vegetables are just tender.
  4. Step 4: Return the beef to the wok; pour 3 tbsp soy sauce over the mixture, stirring to coat everything evenly; cook for another 1-2 minutes until heated through and sauce slightly thickens.
  5. Step 5: Season with 1/2 tsp salt and 1/4 tsp black pepper; remove from heat and serve immediately.
