Mix bar b q sauce with canned tuna, then put it onto a cracker, low sodium triscuits are my fav but Im sure others would be just as good.
The cool thing is bar b q sauce has no fat unlike mayo which I used to use. I actually raided my kitchen for a snack last week and that was all I could find, now Ive been eating it all the time. Sounds gross I know, but try it!
