Instructions
- Step 1: In a medium bowl, toss 1 lb thinly sliced flank steak with 2 tbsp cornstarch and 1 tbsp soy sauce until evenly coated. Let marinate 10 minutes.
- 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 slightly pink inside. Remove beef and set aside.
- Step 3: Lower heat to medium-high and add 1 tbsp sesame oil. Add 1 tbsp minced fresh ginger and 2 minced garlic cloves, stir-frying for 30 seconds until fragrant.
- Step 4: Add 1 large julienned red bell pepper and 1 large julienned green bell pepper to the wok, stir-frying for 3-4 minutes until tender-crisp.
- Step 5: Return the beef to the wok. Stir in 2 tbsp soy sauce, 1/2 tsp red chili flakes, and 1 tsp brown sugar. Toss everything together and cook for 1-2 minutes until sauce thickens and coats the beef and vegetables.
