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.
I had something like that once from Aldi. It said on the package to heat it in the microwave. I figured it couldn't hurt to follow the instructions... It was so incredibly bad...
I was already upset at the frozen sushi but you just had to go and make this microwave sushi comment. I think I'm done for the night.
I saw it on Lidl. I looked disgusting.
You're braver than I'll ever be for trying.
