Instructions

  1. Step 1: Heat 1 tbsp olive oil in a large skillet or wok over high heat until shimmering. Add 1/2 cup raw cashew nuts and toast for 2 minutes until golden, stirring constantly. Remove cashews and set aside.
  2. Step 2: Add remaining 1 tbsp olive oil and 2 tbsp sesame oil to the skillet. Add 1 lb thinly sliced flank steak seasoned with 1/2 tsp sea salt and 1/4 tsp black pepper. Stir-fry for 3-4 minutes until browned but still tender. Remove beef and set aside.
  3. Step 3: In the same skillet, add 3 cups broccoli florets, 3 minced garlic cloves, and 1 tbsp grated fresh ginger. Stir-fry for 4-5 minutes until broccoli is bright green and tender-crisp.
  4. Step 4: Return beef and toasted cashews to the skillet. Pour in 3 tbsp coconut aminos and sprinkle 1/4 tsp red chili flakes and remaining 1/2 tsp sea salt. Stir everything together and cook for 2 more minutes until sauce coats all ingredients and is fragrant.
  5. Step 5: Serve hot immediately for a satisfying Whole30-compliant beef stir-fry.
