Instructions

  1. Step 1: Heat 1 tbsp sesame oil in a large wok or skillet over high heat until shimmering. Add 1 lb thinly sliced flank steak and stir-fry for 2-3 minutes until browned but not fully cooked. Remove and set aside.
  2. Step 2: In the same pan, add the remaining 1 tbsp sesame oil. Add 3 cups broccoli florets and stir-fry for 4-5 minutes until crisp-tender.
  3. Step 3: Add 1 tbsp grated fresh ginger and 3 minced garlic cloves, stir-frying for 30 seconds until fragrant.
  4. Step 4: Return the beef to the pan. Pour in 1/4 cup soy sauce, 1 tbsp rice vinegar, 1 tsp erythritol, and 1/4 tsp red pepper flakes. Toss everything together and cook for another 2 minutes until the sauce thickens slightly and coats the beef and broccoli.
  5. Step 5: Remove from heat and garnish with 2 sliced green onions and 1 tbsp toasted sesame seeds before serving.
