Instructions

Step 1: Toss 1 lb thinly sliced flank steak with 1 tsp cornstarch and 1/4 tsp black pepper until evenly coated.
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 and set aside.
Step 3: Add remaining 1 tbsp vegetable oil to the wok, then add 4 minced garlic cloves and 12 oz trimmed green beans. Stir-fry for 3-4 minutes until the beans are bright green and just tender.
Step 4: Return the beef to the wok. Stir in 3 tbsp oyster sauce, 1 tbsp soy sauce, 1 tsp brown sugar, and 1/4 cup water. Cook for 1-2 minutes until the sauce thickens slightly and coats the beef and beans.
Step 5: Remove from heat and serve immediately with steamed rice if desired.
