Instructions

1. Step 1: In a medium bowl, toss 12 oz thinly sliced flank steak with 1 tbsp cornstarch and 1/2 tsp ground black pepper until evenly coated; set aside.

5. Step 5: Add 3 cups broccoli florets and 1 cup sliced shiitake mushrooms, stir-frying for 4-5 minutes until broccoli is bright green and slightly tender.
6. Step 6: Return the cooked beef to the wok, pour in the prepared sauce, and toss everything together over medium-high heat for 2-3 minutes until the sauce thickens and coats all ingredients.
7. Step 7: Drizzle 1 tsp sesame oil over the stir-fry, toss once more, then remove from heat. Garnish with 2 sliced green onions before serving immediately.
