Yes there is a walmart, but only one actual grocery store, and it now stock frozen sushi.
Update: I shared this picture with my local gaming group, one of them went and picked up a tray.
He tossed it into the fridge and tried it this morning.
I had the first piece. It is supposed to be "Refrigerated Only" by the packaging, but honestly, with a fridge thaw, it tastes just fine. I've had plenty worse than that.
If I was not vegetarian I would give it a try. The closest place to get sushi to us is an hour drive.
That seems like it's supposed to be the grab and go kind that's not frozen when you buy it.
I see these at 7/11 just with a different label. I'm sure it's all from the same factory.
If it's gonna be previously-frozen sushi, better it should still be frozen so at least you know when you started thawing it out.
It's typically just the fish that was previously frozen, and that's to kill any parasites. I've never seen the entire maki roll frozen lmao, of course that will be bad.
Yes it's definitely not ideal. But in a wasteland with no sushi at all I suppose it's... something. Freezing would help keep the rice from becoming dangerous, as well as the surimi and mayo. But it's not great for texture.
