Ingredients

Instructions

  1. Step 1: In a small bowl, whisk together 3 tbsp soy sauce, 1 tbsp Worcestershire sauce, 1 tbsp brown sugar, and 1 tsp cornstarch until smooth.
  2. Step 2: Heat 2 tbsp vegetable oil in a large skillet or wok over medium-high heat until shimmering. Add 1 lb thinly sliced flank steak and stir-fry for 3-4 minutes until just browned but still tender. Remove beef and set aside.
  3. Step 3: In the same skillet, add 1 medium thinly sliced yellow onion, 1 large red bell pepper julienned, and 1 large green bell pepper julienned. Stir-fry for 4-5 minutes until vegetables are crisp-tender.
  4. Step 4: Add 3 minced garlic cloves and 2 tbsp chopped hot giardiniera peppers (if using), cook for 30 seconds until fragrant.
  5. Step 5: Return the beef to the skillet and pour in the prepared sauce. Stir continuously for 2-3 minutes until the sauce thickens and coats all ingredients.
  6. Step 6: Serve the stir fry over 4 cups cooked white rice and garnish with 2 tbsp chopped fresh parsley.
