Seaweed salad sushi calories?

Does anyone have any idea how many calories is in one piece of seaweed salad sushi? It had seaweed salad and white rice inside.

They look like this:
(Don't open that if you're hungry haha they look quite tasty.)

It's getting really hard to log now that it's the holidays and the fact that the calories for what I've eaten isn't coming up with a MFP database search or a google search is making it really tempting to just give up logging, but I'm hanging in there. Damn you holidays. :/
