Tuna Crostini

I made this with Ariella with leftover fibrous tuna. She scarfed it - absolutely delicious and our little secret (well no more). Uses leftover firous parts of tuna if you want, avoiding waste.

1/8 lb sashimi quality tuna
1/2 sweet onion roasted with chicken, crushed and minced
French olive oil (buttery)
3 sprigs thyme, minced
fleur de sel - crushed with flat of knife.
pepper
8 slices fresh bread - I used Puglian bread

1. slice tuna, crush with flat of knife and remove any fibrous parts.
