I was walking home today when I passed Angelo and Angelina deep in discussion about some greenery Angelo was waving about. It turned out his brother had been asked to buy some chicory seeds (in Italy?) and had bought what ended up as this green vegetable. Neither of them knew what it could be. Angelina gave me a bundle to grow, though I'm not sure I want to fill my allotment with more bitter Italian greens. It tasted hot rather than bitter, so I would guess it's a member of the radish family.
