The real recipe here is for the sauce, which turned out to be a great, simple and fresh sauce that in the processor develops a creamy texture. Works well for fish and salad, probably chicken also.
The tuna steaks we bought here were a little stingy, given the price. But of good quality. Cooked on the BBQ for a few minutes each side.
