Instructions

  1. Step 1: Heat 1 tbsp avocado oil in a large skillet over high heat until shimmering. Add 1 lb grass-fed beef sirloin strips seasoned with 1/2 tsp sea salt and 1/4 tsp black pepper, and stir-fry for 3-4 minutes until browned but slightly pink inside. Remove beef and set aside.
  2. Step 2: Add remaining 1 tbsp avocado oil to the skillet. Add 3 minced garlic cloves and 1 tbsp grated fresh ginger, sauté for 30 seconds until fragrant.
  3. Step 3: Add 1 large sliced red bell pepper, 1 large sliced yellow bell pepper, and 2 medium sliced zucchini half-moons. Stir-fry for 5-6 minutes until vegetables are tender-crisp.
  4. Step 4: Return beef to the skillet. Pour in 3 tbsp coconut aminos and sprinkle 1/4 tsp red chili flakes. Stir everything together and cook for 2 more minutes until sauce coats beef and vegetables well. Adjust seasoning with remaining 1/2 tsp sea salt as needed.
  5. Step 5: Serve hot, garnished with fresh herbs if desired.
