Ingredients

Instructions

  1. Step 1: Heat 1 tbsp extra virgin olive oil in a large nonstick skillet over medium-high heat. Season 4 salmon fillets with 1/2 tsp sea salt and 1/4 tsp freshly ground black pepper. Place fillets skin side down and cook for 5-6 minutes until skin is crisp, then flip and cook another 3-4 minutes until salmon is opaque and flakes easily.
  2. Step 2: Remove salmon from skillet and keep warm. In the same skillet, add 1 tbsp extra virgin olive oil and 3 minced garlic cloves. Sauté for 30 seconds until fragrant.
  3. Step 3: Add 2 tbsp rinsed capers and 3 tbsp fresh lemon juice to the skillet. Let the sauce simmer gently for 1-2 minutes until slightly reduced, then stir in 2 tbsp chopped fresh parsley.
  4. Step 4: In a separate large skillet, heat 1 tbsp olive oil over medium heat. Add 6 cups baby spinach leaves and 1/2 tsp sea salt, cooking and stirring for 2-3 minutes until wilted but still vibrant green.
  5. Step 5: Serve each salmon fillet topped with a spoonful of lemon-caper sauce alongside the sautéed spinach for a fresh and nutritious Whole30 meal.
