  • 2 garlic cloves, peeled and finely chopped

  2. Season with salt and pepper and spray each fish, on both sides, with low calorie cooking spray.
  3. Preheat the grill or barbecue and, when hot, cook the fish for 5-7 minutes on each side or until the skin is crisp and lightly charred at the edges and the fish is just tender.
  4. While the fish is under the grill, combine the lemon juice, spring onions, dried chilli flakes, rosemary and orange juice in a small bowl.
  5. Drizzle the rosemary mixture over the mackerel and serve straight from the grill.

Tip: Serve with a crisp mixed leaf salad.
