IMO the Albacore has a stronger fish taste/smell than the regular tuna. It's also more expensive.
It may sound gross but I like to throw some sweet pickle relish into my plain tuna. It helps get it down. NO MAYO...
Sliced Turkey breast from the Deli is a great change of pace.
Also I buy those little frozen containers of plain Egg Whites(not egg beaters) and cook them up with maybe one whole egg. Some people just throw them into thier MR shake. I cook a bunch of it scrambled style and put it in containers for at work.
