Ingredients

Instructions

  1. Step 1: Toss 12 oz thinly sliced beef sirloin with 3 tbsp soy sauce and 1 tbsp cornstarch in a bowl until evenly coated.
  2. Step 2: Heat 2 tbsp vegetable oil in a wok or large skillet over high heat until shimmering. Add the beef in a single layer and stir-fry for 2-3 minutes until browned but not fully cooked. Remove beef and set aside.
  3. Step 3: In the same wok, add 5 minced garlic cloves, 1 tbsp minced ginger, and 1/2 tsp red chili flakes. Stir-fry for 30 seconds until fragrant.
  4. Step 4: Add 1 large each of red, yellow, and green bell peppers sliced into thin strips. Stir-fry for 3-4 minutes until peppers are tender-crisp.
  5. Step 5: Return the beef to the wok along with 1 tbsp brown sugar, 1 tbsp rice vinegar, and 1/4 cup water. Stir-fry everything together for 2 minutes until the sauce thickens and coats the beef and peppers.
  6. Step 6: Remove from heat and garnish with 2 sliced green onions before serving over steamed rice or noodles.
