Instructions

1. Step 1: In a bowl, whisk together 2 tbsp gochujang, 3 tbsp soy sauce, 2 tsp sesame oil, 1 tbsp brown sugar, 3 minced garlic cloves, and 1 tbsp minced fresh ginger until smooth. Add 1 lb thinly sliced flank steak and marinate for 15 minutes.
2. Step 2: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add the marinated beef strips in a single layer and sear for 2 minutes without stirring, then stir-fry for another 2 minutes until browned but still tender. Remove beef and set aside.
3. Step 3: In the same pan, add 1 large julienned carrot, 1 medium thinly sliced red bell pepper, and 1 medium julienned zucchini. Stir-fry for 3-4 minutes until vegetables are crisp-tender.
4. Step 4: Return the beef to the pan with vegetables, add 3 chopped green onions, and toss everything together over high heat for 1-2 minutes until heated through and sauce coats all ingredients. Sprinkle 1 tbsp toasted sesame seeds on top and serve immediately over steamed white rice if desired.
