Checking to see if your sushi is fresh is incredibly important if you want to ensure that it's safe to eat, so it stands to reason that picking up a box of gas station sushi isn't the best idea. However, the general rule of thumb that you shouldn't eat gas station sushi doesn't apply in certain places — like Hawaii.

Sushi is a big part of Hawaiian cuisine, and though there are countless locations where you can enjoy it there, you don't need to look any further than 7-Eleven. Perhaps the most instantly recognizable dish you can purchase at 7-Eleven Hawaii is nori rolls, made from a type of edible seaweed called nori.

At Hawaiian 7-Elevens, you can find sushi dishes like nori rolls, spicy ahi and shoyu tuna rolls, and Spam musubi, a snack that combines fried Spam with rice and nori to make a sushi-like roll. Their ahi tuna is caught using longline fishing, as opposed to net fishing, which causes less stress on the fish and increases its shelf life.
