Instructions: Roughly chop the tomatoes, pepper and chilli and place in a bowl. Cut the avocado in half and, with your hand wrapped in a tea towel for protection, hold the half with the stone in it. Lightly tap the stone with a sharp knife so that the blade lodges in the stone. Twist the knife and the stone should come away easily. Slice the flesh from both halves into chunks and add to the chopped ingredients. Pour over a generous amount of olive oil, season with salt and pepper and set aside.

Grill the tuna steaks for two minutes on each side, or longer if you dont want them too underdone. Remember that the fish will continue cooking a little even when you remove it from the heat. Season with salt and pepper on both sides and allow to rest in a warm oven.

To serve, divide the salsa equally on four plates, place the tuna steaks on top, sprinkle with the chives and coriander and serve with half a lemon or lime.
