Nadia's spinach and ricotta pie

It's National Pie Week - and, as always, our Nadia likes to mix things up a bit and has veered away from British classics to bring us a Greek-inspired dish.

This spinach and ricotta pie is better known as Spanikopita and is much healthier than a normal pie as it uses filo pastry, which has about half the fat of puff pastry.

You can also make small triangular versions - like little samosas!
