Classic Tuna
Okay, so fish is already one of the most pretentious kinds of meals out there. Luckily, Subway gets a green vote here for using skipjack tuna which only comes from legal fishing. The problem with this sandwich is in fact its tremendous quantity of mayonnaise. First of all, it kills the texture and taste of the fish, which already makes it pointless. Secondly, it contains 25 grams of fat, 4.5 grams of which are saturated.
