Grilled tuna with mango and avocado

I had a fantastic meal this afternoon - and my wife had something else to eat.  We've been together for quite a while now and we do agree on most things.  But my wife doesn't like tuna unless it's been canned.  So today I gave up, prepared some fresh tuna (well. it's been frozen) for myself.  When my wife saw my plate she said: Do you think I could have just one tiny bit of your tuna?  And then she said: Mmm.
