Instructions

  1. Step 1: Pat dry 4 mackerel fillets and season both sides with salt and black pepper.

  4. Step 4: In a medium bowl, combine 1 cup quartered cherry tomatoes, 1/2 cup chopped kalamata olives, 1/4 cup finely chopped red onion, 1 tbsp rinsed capers, 2 tbsp chopped fresh basil, 1 tsp lemon zest, 1 tbsp lemon juice, and 1 tbsp extra virgin olive oil. Mix gently and season with salt and black pepper to taste.
  5. Step 5: Spoon the tomato and olive tapenade over the warm mackerel fillets and serve immediately.
