I mix it with fat free vanilla yogurt and mustard. It's a mayo substitute that I read about in Muscle Media 2000 a couple of years ago. It's not too bad, especially with some onions and celery mixed in!
What I've been doing is either mixing Green Chili in to my tuna ( I personally love it) or mixing 2 cans of tuna with brown rice, salsa and lime...Yummm
Wrapping it in the same seaweed stuff that they make sushi with, really makes it easier to get down.... it disguises the taste and the texture, which is the whole problem with canned tuna.
Just take little bits from the can, lay it on a sheet of seaweed, roll it up and eat....
You know what I do? When I strain it I squish it up really well and then I just take a big bunch, stick it in my mouth and swallow it with a big sip of water. I can get down two cans in about 2.5-3 minutes. Piece of cake.
