A temaki (hand roll) is usually fish fillet, veggies and a little bit of rice wrapped in nori. Sometimes I just don't have all the ingredients handy and this is the result. It's not very pretty but it's fast to cook (took me about 5 min to make it) and delicious (oh and healthy, but I think that boat has sailed when I started bringing blocks of cheese for lunch)...
Stuff for stuffing:
1/2 can of tuna (rest went to the cats of course)
I zapped the stuff in the microwave for about 4 min, topped it with furikake (rice seasoning consist of dried fish, eggs, pieces of nori and sesame) and wrapped them up in nori.
