Remove the bones from mackerel and cut into smaller pieces. Put the soy sauce, wine, sugar, garlic powder, cheese, salt and pepper into a bowl and mix well. Add in the chopped mackerel pieces. Marinate for at least 30 min or half a day in the fridge.

Cut the greens into bite sized pieces.

Just before frying, coat each mackerel with flour, heat oil in a saucepan and fry the mackerel until it begins to crisp. Turn and fry until well cooked. Once cooked, place the fish on a plate with paper towels to soak up excess oil.

Using a clean frying pan, add 1 Tbsp of olive oil, and once heated, put in the vegetables and stir fry on medium heat for a minute, then add the fried mackerel. Shake the pan a little to mix it up, but not too much. Finally, pour in 1 Tbsp balsamic vinegar, season with salt and pepper if needed.
