Instructions

1. Step 1: In a bowl, combine 1 lb thinly sliced flank steak, 3 tbsp soy sauce, and 1 tbsp cornstarch. Toss to coat the beef evenly and set aside for 10 minutes.
2. Step 2: Heat 2 tbsp vegetable oil and 2 tbsp sesame oil in a large wok or skillet over high heat until shimmering. Add the marinated beef in a single layer and stir-fry for 2-3 minutes until browned but not fully cooked. Remove beef and set aside.
3. Step 3: In the same wok, add 4 minced garlic cloves, 1 tbsp grated fresh ginger, 1 tsp ground cumin, and 1 tsp ground coriander. Stir-fry for 30 seconds until fragrant.
4. Step 4: Add 1 large sliced red bell pepper and 1 large sliced yellow bell pepper, stir-frying for 3-4 minutes until peppers are crisp-tender.
5. Step 5: Return the beef to the wok along with 1/4 tsp red chili flakes, 1/2 tsp salt, and 1/2 tsp freshly ground black pepper. Stir-fry everything together for another 2 minutes until the beef is cooked through and the spices are well combined.
6. Step 6: Remove from heat and garnish with 1/4 cup chopped green onions. Serve immediately with steamed rice or noodles.
