Instructions: Preheat the oven to 400F/200C degrees.

Rub the tuna steaks with 1 tblsp olive oil and season lightly with pepper.

Slice onion fine.

In a large frying pan, saute the onion in the remaining oil until it is limp. Add chopped tomatoes and vermouth and cook briefly.

Place the steaks in a shallow baking dish, pour on the onion/tomato mixture, and bake about 20 minutes, covered, depending on the thickness of the tuna steaks.

Fish will flake easily when cooked through;

Sprinkle with basil and serve.

Other varieties of fish can also be used in place of tuna. eg trevally, blue eye, snapper etc.
