Ingredients

12 oz flank steak
2 tbsp soy sauce
1 tbsp rice vinegar
1 tbsp cornstarch
1 tbsp sesame oil
2 tbsp vegetable oil
2 cups broccoli florets
1 red bell pepper
1 medium carrot
3 cloves garlic
1 tbsp ginger
1/4 cup chicken broth
2 tbsp oyster sauce
1 tbsp sugar
1/2 tsp black pepper
2 tbsp green onions

Instructions

Step 1: In a bowl, combine 12 oz flank steak (thinly sliced), 2 tbsp soy sauce, 1 tbsp rice vinegar, and 1 tbsp cornstarch. Let marinate for 15 minutes while preparing other ingredients.
Step 2: Heat 2 tbsp vegetable oil in a wok or large skillet over high heat until shimmering. Add the marinated flank steak and stir-fry for 2-3 minutes until browned on the outside but still pink inside; remove and set aside.
Step 3: Add 1 tbsp sesame oil to the wok, then add 3 cloves garlic (minced) and 1 tbsp fresh ginger (minced), stir-frying for 30 seconds until fragrant.
Step 4: Add 2 cups broccoli florets, 1 red bell pepper (thinly sliced), and 1 medium carrot (julienned) to the wok, and stir-fry for 3-4 minutes until crisp-tender.
Step 5: In a small bowl, mix 1/4 cup chicken broth, 2 tbsp oyster sauce, 1 tbsp sugar, and 1/2 tsp black pepper. Pour the sauce into the wok and bring to a simmer.
Step 6: Return the cooked flank steak to the wok and stir to coat, cooking for 1 more minute until the sauce thickens and coats the beef and vegetables.
Step 7: Serve immediately over 2 cups cooked rice, garnished with 2 tbsp green onions.
