Instructions

  1. Step 1: Pat dry 4 cod fillets (about 6 oz each) and season both sides with 3/4 tsp sea salt and 1/2 tsp black pepper. Heat 2 tbsp extra virgin olive oil in a large skillet over medium heat. Add cod fillets and sauté for 4-5 minutes per side until opaque and easily flaked with a fork. Remove cod and keep warm.
  2. Step 2: In the same skillet, add 1 tbsp olive oil and 4 minced garlic cloves, sautéing for 30 seconds until fragrant. Add 6 cups fresh spinach leaves and 1.5 cups halved cherry tomatoes with 1/2 tsp sea salt and 1/4 tsp black pepper. Cook for 3-4 minutes, stirring frequently, until spinach is wilted and tomatoes soften.
  3. Step 3: Stir in 2 tbsp freshly squeezed lemon juice to the spinach and tomatoes, then serve alongside the cod fillets.
