If you're looking for something easy and simple but with a bit of a 'wow factor' to impress guests with, this pear, feta and walnut tart could be it. Unroll ready-made puff pastry, add the toppings, and bake!
Lay the pastry sheet out on a baking tray lined with baking paper (trim the pastry slightly if you need to), then score a 1.5 – 2cm border all the way around the edge with a knife (taking care not to cut all the way through).
Bake for 7 minutes until the pastry is all puffed up, then remove from the oven.
Push the inside of the tart down inside the border, then spread the crème fraiche / sour cream all over this part. Add the pear slices in an overlapping pattern, then return the tart to the oven for 15 minutes until golden and risen.
Remove the tart from the oven again and crumble over the feta and sprinkle over the walnuts. Bake for another 5 minutes.
To serve, drizzle over a little honey, grind over some black pepper, and scatter over a few rocket / arugula leaves.
Serve with a simple rocket / arugula salad.
Notes
Try to use firm pears. If they're too ripe, you'll risk making the pastry soggy.
