Looking for the best thing since rolled rice? Try sushi in a tube! We thought the food in a tube thing was gross when Gogurt did it, but sushi in a tube may be crossing a new line. Normally it’s not even a good idea to take sushi home from a restaurant because it goes bad so quickly but the sushi in each Sushi Popper has been sealed and frozen and is good for up to three months after you buy it. Sushi Popper is available in a ton of raw and cooked fish flavors as well as vegetarian and dessert varieties.
