What have I been eating?

So I bought some seedlings from a market ages ago, a few labelled mustard greens and a few labelled Warrigal greens. I’ve been eating the leaves and was pretty sure all the mustard greens got stir fried. What I thought was Warrigal greens weren’t great and got overgrown. Just pulled them out and found a turip looking thing on the bottom.

Any idea what I’ve got and what leaves I’ve been eating? And should I continue eating the tasty looking root?
