Smashed Roasted Jerusalem Artichokes

I've become quite fond of Jerusalem artichokes (or sunchokes) after receiving the first set from the CSA box. These odd looking vegetables look almost like ginger, but are closer to potatoes, with a nutty and almost sweet flavour. This simple preparation highlights the great taste of the chokes.
