Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Add 1 lb thinly sliced flank steak seasoned with 1/2 tsp sea salt and 1/4 tsp black pepper. Sauté for 3-4 minutes, stirring frequently, until beef is browned but still tender. Remove beef from skillet and set aside.
  2. Step 2: In the same skillet, add 1 tbsp olive oil and 4 minced garlic cloves. Sauté for 30 seconds until fragrant without browning.
  3. Step 3: Add 3 medium zucchini ribbons and season with 1/2 tsp sea salt, 1/4 tsp black pepper, and 1/4 tsp red chili flakes if using. Cook, stirring occasionally, for 4-5 minutes until zucchini is tender but still bright green.
  4. Step 4: Return the cooked beef to the skillet and toss with 1/2 cup chopped fresh basil leaves. Cook together for 1-2 minutes until basil is wilted and everything is heated through.
  5. Step 5: Serve immediately while warm for a quick, nutrient-packed meal.
