Cans of tuna are more palatable if you stir something into them, like a small amount of low fat Italian dressing (or some homemade w/olive oil, maybe?), some soy or oyster sauce, or even good ole fashoined fat-free mayo. I’ve also added spices to it and that really helps. Rotisserie chicken seasoning is great stuff, or seasoned salt, if you are waiting for a visit from the Sodium Fairy. Canned salmon’s great too, and the tuna and salmon packet thingys- they tend to taste fresher, I think.
It’s not the taste that gets me so much as the occasional scale or bone chip in there. Yick. Enjoy!
