Ingredients

Instructions

  1. Step 1: Heat 1 tbsp olive oil in a large skillet or wok over medium-high heat. Add 12 oz thinly sliced flank steak and cook for 2-3 minutes until browned but still tender, then transfer to a plate.
  2. Step 2: In the same skillet, add 2 tbsp sesame oil and 3 cups broccoli florets. Stir-fry for 4-5 minutes until broccoli is bright green and crisp-tender.
  3. Step 3: Add 3 minced garlic cloves, 1 tsp grated ginger, and 1/4 tsp red pepper flakes to the broccoli. Stir-fry for 30 seconds until fragrant.
  4. Step 4: Return the beef to the skillet, add 3 tbsp soy sauce and 1 tbsp rice vinegar, tossing everything together for 1-2 minutes until heated through and sauce coats the ingredients.
  5. Step 5: Remove from heat and garnish with 2 sliced green onions and 1 tbsp sesame seeds before serving.
