Instructions

Step 1: Heat 2 tbsp vegetable oil in a large wok over high heat until shimmering. Add 8 oz thinly sliced lean beef sirloin and sauté for 2-3 minutes until browned but not fully cooked. Remove beef and set aside.
Step 2: In the same wok, add 3 minced garlic cloves and 1 tbsp grated fresh ginger, stir-frying for 30 seconds until fragrant.
Step 3: Add 2 cups broccoli florets and 1 thinly sliced red bell pepper, stir-frying for 4-5 minutes until vegetables are crisp-tender.
Step 4: Return beef to the wok along with 1/4 cup soy sauce, 1 tbsp sesame oil, 1/2 tsp salt, and 1/4 tsp red pepper flakes if using. Stir in 1 tsp cornstarch dissolved in 2 tbsp water and cook for 1-2 minutes until the sauce thickens and coats all ingredients.
Step 5: Remove from heat, sprinkle 2 chopped green onions on top, and serve immediately with steamed rice or noodles.
