If you're making tuna patties, use a slice.  If you're making tuna salad, use the chopped ones.  But put 4 or 5 paper towels in the sink and pour the crushed pineapple on them.  Squeeze out the juice; otherwise, your tuna salad can be ingested with a straw! 

Thank you, GB.  So, I take it you have tried tuna & pineapple?  

Definitely sounds like something I'll like. Just never thought to try it.
