Vegan sushi is perhaps even tastier the next day.
Try to cut your sushi rolls as needed. If you have leftover sushi, you want it to still be a whole roll. Sushi with raw fish should not be kept for more than a day, vegan sushi, is perhaps even tastier the next day. It should last about four days. I like to dip mine in the leftover tofu marinade, along with some wasabi and pickled ginger.
