Cut the eggplant into slices approximately 5mm thick. Pour ½ cup berry dressing over it to marinate for between 30 minutes and an hour.
Heat the oven to 200 degrees Celsius.
Lay the eggplant on a flat baking sheet and cook for 15 minutes until golden. While the eggplant is cooking brush the kingfish with olive oil and seasoning and in a large frying pan sear the fish on each side. Reduce the oven temperature to 180C and place the fish on a flat baking tray in the oven to cook with the eggplant for a further 10 minutes.
Steam the spinach and serve with the eggplant and kingfish.
