Tuna Steaks with Green Chilli Pesto

This is a lovely tuna steak recipe. I remember watching it as a demonstration back when I did my Leith's course about 10 years ago! It is a very tasty dish but really simple. I served it with pasta and spinach

Grilled Tuna Steaks with Green Chilli Pesto (from Leiths Fish Bible)
(Serves 4)

4 tuna steaks
6 tbsp oil
2 tbsp balsamic vinegar
pepper

For the chilli pesto
2 green chillies, deseeded and roughly chopped
1 bunch coriander
55g pinenuts
2 cloves garlic, crushed
55g parmesan cheese, grated
6 tbsp olive oil
salt and pepper

Put the tuna steaks into a bowl or bag and pour over the oil, balsamic vinegar and pepper. Leave to marinate for 30 mins.

Preheat the grill on high.

Make the chilli pesto: Put the chillies, coriander, pinenuts and garlic into a food processor. Blend well and add the cheese. With the motor running pour the oil in a thin stream until well emulsified. Season with salt and pepper

Grill the tuna for 2-3 mins each side until cooked. Serve.
