If it’s fresh tuna and cooked rare, then fine.
If it’s canned, I’ll only eat it straight out of the can or mixed with celery, onions and dill pickles or relish, on literally whole wheat bread.
Can’t stand white bread or fake whole wheat.
My bread needs to be dense and then, so I can 75% of the calories, I’ll sometimes cut the edges off, justifying another drink.
I’m into portugese rolls...and soleil bread.
They now have tuna in little glass jars that aren't bad.
