Grilled Mackerel with Chargrilled Potatoes is a delicious and healthy dish that combines the rich flavors of mackerel with the smoky taste of chargrilled potatoes. The mackerel is marinated in a tangy mixture of lemon juice, garlic, and herbs, then grilled to perfection. The potatoes are sliced and cooked on a hot grill until they are crispy on the outside and tender on the inside. This dish is perfect for a summer barbecue or a quick and easy weeknight dinner.
