Wash the hijiki thoroughly and prepare it.
Mash the tofu and mix well with the hijiki.
Add egg, julienned carrots, green onion, salt, and pepper, and mix evenly.
Spread the hijiki-tofu mixture widely on a sheet of seaweed, then roll it up like gimbap.
Add oil to a frying pan and cook the rolled sushi over low heat, turning occasionally until golden brown on all sides.
Slice into bite-sized pieces and arrange on a plate.
