Instructions

  1. Step 1: In a small bowl, whisk together 2 tbsp coconut aminos, 1 tbsp sesame oil, 1/4 cup water, 1 tsp cornstarch, 1/4 tsp black pepper, and 1/8 tsp red pepper flakes until smooth.
  2. Step 2: Heat 1 tbsp olive oil in a large skillet over medium-high heat until shimmering (about 350°F).
  3. Step 3: Add 12 oz thinly sliced flank steak to the skillet and cook for 2-3 minutes per side until browned but still slightly pink in the center; remove the beef and set aside.
  4. Step 4: Add 2 cups broccoli florets to the skillet and stir-fry for 3-4 minutes until bright green and crisp-tender.

  6. Step 6: Return the beef to the skillet, pour in the sauce mixture, and stir to coat. Cook for 1-2 minutes until the sauce thickens and coats the back of a spoon.
  7. Step 7: Garnish with 2 tbsp sliced green onions and serve immediately.
