Instructions

1. Step 1: In a medium bowl, toss 1 lb thinly sliced flank steak with 2 tbsp coconut aminos, 1/2 tsp sea salt, and 1/4 tsp black pepper; set aside to marinate for 10 minutes.
2. Step 2: Heat 2 tbsp extra virgin olive oil in a large wok or skillet over high heat until shimmering.
3. Step 3: Add the marinated beef in a single layer and sear for 2 minutes without stirring to develop a crust, then stir-fry for another 2 minutes until mostly cooked. Remove beef from the pan and set aside.
4. Step 4: In the same pan, add 1 tbsp sesame oil, then add 4 minced garlic cloves and 1 tbsp grated fresh ginger. Stir-fry for 30 seconds until fragrant.
5. Step 5: Add 1 large each of thinly sliced red, yellow, and green bell peppers along with 1/2 tsp sea salt and 1/4 tsp black pepper. Stir-fry for 4-5 minutes until peppers are tender-crisp.
6. Step 6: Return the beef to the pan, add the remaining 1 tbsp coconut aminos and 1/4 tsp red chili flakes if using. Stir-fry everything together for another 1-2 minutes until beef is cooked through and sauce coats the vegetables.
7. Step 7: Remove from heat and garnish with 2 sliced green onions before serving.
