Instructions
- Step 1: In a medium bowl, toss 1 lb thinly sliced flank steak with 3 tbsp soy sauce and 1 tbsp cornstarch until evenly coated. Let marinate for 10 minutes.
- Step 2: Heat 2 tbsp vegetable oil in a wok or large skillet over high heat until shimmering. Add the marinated beef in a single layer and stir-fry for 2-3 minutes until browned but still tender. Remove beef from wok and set aside.

- Step 5: Stir together 1 tbsp brown sugar, 1 tbsp rice vinegar, and 1/4 cup water in a small bowl, then pour into the wok. Cook for 2 minutes until sauce thickens and coats the vegetables.
- Step 6: Return the cooked beef to the wok, drizzle with 1 tsp sesame oil, and toss everything together over medium heat for 1 minute to combine flavors.
- Step 7: Remove from heat, garnish with 2 sliced green onions, and serve immediately over steamed rice or noodles.
