This grilled bluefish with tomato and herbs is a vibrant, flavourful dish that celebrates the natural richness of oily fish. By topping the fillets with a zesty herb mayonnaise and thick slices of fresh tomato, the fish remains beautifully moist under the grill. The combination of dill and chives adds a bright, aromatic lift that balances the savoury depth of the mackerel or bluefish, creating a simple yet sophisticated main course.
