After SWMBO complained to me that I always bought the same old vegetables (cauliflour, broccoli, carrots, asparagus, etc.) I went to the local market* and returned with, among other things, the attached mystery vegetable.

Can anybody tell me what this is, and how to prepare it? It is about five inches across.

*The local market is amazing. Every Wednesday they close down three blocks of a local street, and the market sets up with stalls, tents, wandering musicians (who play for tips), beggars, selling everything from watch batteries to original oil paintings, and of course food of every description. By 9am it is open for business, by 3pm it is gone without a trace, and for six hours it is so crowded you have to squeeze sideways through tiny gaps to traverse it.
