Instructions

1. Step 1: In a small bowl, whisk together 3 tbsp soy sauce, 1 tbsp brown sugar, 1 tsp cornstarch, and 2 tbsp water until smooth and set aside.
2. Step 2: Heat 2 tbsp vegetable oil in a large skillet over medium-high heat until shimmering. Add 12 oz thinly sliced beef sirloin and cook for 2-3 minutes, stirring frequently, until browned but not fully cooked. Remove beef and set aside.
3. Step 3: In the same skillet, add 3 minced garlic cloves and sauté for 30 seconds until fragrant. Add 1 sliced red bell pepper and 1 sliced yellow bell pepper, cooking for 4-5 minutes until just tender but still crisp.
4. Step 4: Return the beef to the skillet, pour in the soy sauce mixture, then add 2 tsp sesame oil and 1/4 tsp black pepper. Stir constantly for 2 minutes until the sauce thickens and coats the beef and vegetables.
5. Step 5: Remove from heat and sprinkle with 2 thinly sliced green onions before serving immediately over rice or noodles.
