Instructions: In a bowl or container mix together the ginger, garlic, lime juice and olive oil with a little salt and pepper. Place the tuna steaks in this mixture and leave to marinade for 10 minutes.

Meanwhile to make the dressing simply mix the vinegar and sugar together in a saucepan and bring to a vigorous boil. Once the solution has boiled for 5 minutes take off the heat and leave to cool slightly.

Peel and dice the pineapple into a small sized dice and mix with the chilli then add both ingredients to the vinegar and sugar. Leave to infuse for a few minutes.

Meanwhile place the marinated tuna steaks on the pre-heated grill bars or under a normal grill and cook for 3 minutes each side. Mix together the spinach leaves with some grated apple including the skin. Place this in a serving dish with the tuna steaks on top. For the dressing, just before serving simply add the fresh green coriander leaves to the sweet and sour dressing. Pour this liberally over the steaks or alternatively in a small sauce bowl on the side.
