actually i lied!
the "strangest" thing ive mixed with tuna is an apple!
it tastes amazing too! Just cut up an apple into bite-size pieces, then mix it in with tuna salad. I guarantee you'll like it.
fat free italian dressing is what i find to be the best and i only eat white albacor it is more pricey but if you eat as much as you should it is well worth it.
