What Kind Of Tuna Should I Use For Subway Tuna Sandwich?

I prefer to use tuna packed in water. It is generally healthier than tuna packed in oil. If all you have is tuna packed in oil, squeeze as much liquid out of the tuna as possible.

Some suggest rinsing the tuna with water and pressing it with your tuna lid to remove as much oil as possible.
