"Yeah mum, I'm fine. 'Course I'm eating properly [Pic]

There's a passage in a novel by Aleksandr Solzhenitsyn which explains how prisoners in Chinese prison camps fended-off starvation by eating boiled grass. "It had no nutritional value of course but the one good thing about it was that didn't taste of anything."

Spoiler:

Many years later Golden Wonder found a way to market boiled grass and called it Pot Noodle!
