Goats cheese, leek and walnut tart

We're not big fans of goats cheese but we were given some for free so thought we'd better find a way to use it up. This was surprisingly nice and was very quick and easy to make. Don't forget the onion chutney on the side as it really complemented the other flavours. Pre-heat the oven to 200 degreesLay a piece of baking parchment on an oven proof trayCut the puff pastry into whatever shape and size you want it (we had a small rectangle per person). Lay it on the baking parchment and score a line around the edges, without cutting right through the pastry. Place in the hot oven for around 10 minutes.Meanwhile, fry the diced leeks in a little butter and olive oil until softened (at least 10 minutes). Season the leeks with salt and pepper.Remove the pastry from the oven, and spread the leek mixture out on top. Scatter with the chopped walnuts and then place the goats cheese circles on top. Season again with black pepper before baking in the oven for a further 15-20 minutes, until the goats cheese is bubbling and golden.Serve with a green salad and caremelised onion chutney.
