+1 on the water. Hot sauce is a must. Although we used get the ones packed in mustard, which were tasty.They arn't bad. Im giving up tuna because its so high in mercury so I thought I would try sardines since they have alot of omega 3, low cost, and a good source of protein(and much much lower in mercury).
I get the ones packed in water since I think the oil they use is questionable(especially the really cheap ones). I may add some of my own olive oil or add hot sauce and I have a decent snack.
