Instructions

  1. Step 1: Heat 1 tbsp avocado oil in a large skillet over high heat until shimmering. Add 1 lb thinly sliced flank steak and sear for 2-3 minutes without stirring until browned on one side.

  3. Step 3: Add remaining 1 tbsp avocado oil to the skillet along with 3 minced garlic cloves and 1 tsp grated fresh ginger; sauté for 30 seconds until fragrant.
  4. Step 4: Add 1 large each of sliced red, yellow, and green bell peppers (total about 3 cups) to the skillet and stir fry for 4-5 minutes until tender-crisp.
  5. Step 5: Return beef to the skillet and pour in 3 tbsp coconut aminos; toss everything together and cook for another 1-2 minutes until the sauce is heated through and coats the beef and peppers.
  6. Step 6: Remove from heat and garnish with 1 tsp sesame seeds and 2 sliced green onions before serving.
