This was going to be a glowing explosion of colors, with yellow beets nestling with their pink-and-white striped siblings, and nettle-speckled goat cheese peeking out from underneath. Alas, the candy-striped beets turned out to be... not. I rather want my money back on those.
So instead this is just a sunny repeat of the last post, in pie form: leftover wilted nettles mixed with soft goat cheese under a layer or two of beets, sprinkled with the last of the mint dressing. All contained in a shell of store-bought pastry dough (low fat & partly whole grained - don't do it! or at least, if you have a good recipe for a dough of this kind, let me know!) and baked at 200°C for about half an hour.
Goat cheese works really well with beets, so with a decent crust, this would have been a keeper. If you try this at home, I'd also consider reserving some of the mint vinaigrette to sprinkle on after it comes out of the oven, mostly for aesthetic reasons.
