I have not cared for Tuna for many years....for a while I could not even eat fish...
In the resturant biz...esp. during lent....I made alot of tuna salad on Friday mornings....we used it in "wraps" as well as on grilled sourdough w/cheese as a "tuna melt"
I kept it simple, used a good quality solid canned tuna...mayo and celery...
