Swiss chard roots.

Good morning gardeners, 
Pulling up the Swiss Chard and chopping it up to go into the compost,  (the Memsahib isn't too keen on them) I noticed a similarity between the roots and the roots of beetroot.  Does anyone know if these Chard roots are edible?

Cheers,  Tony.

Doesn't sound like the roots are edible as in taste nice, although you could test and let us know?
I would say beetroot leaves are as good as chard.
And like chard the birds go mad for the beetroot leaves.
Annoying as I have to keep them netted.
