Having now eat the ones we bought, they are definitely just like Oomi noodles.
I looked for and found the protein noodles in Lidl today - not only in the fishy fridge, but on the very top shelf of said fridge. No wonder a shorty like me didn't notice them before.
As our meal plan this week doesn't accommodate the addition of noodles, MrB's issues with fish, and these didn't have a long date on the, I have lobbed them into the freezer. They look like they should freeze OK, although the packaging didn't mention it.
I'll have some when MrB is playing golf and I'm fending for myself. My constitution was built on the Clyde. I'll be fine.
