Top and tail the leek(s) and chop finely into very small pieces. Peel the red onion and finely chop. Sauté the leek and red onion over a low heat in a little olive oil until soft. Tip onto a plate and allow to cool.

In a large bowl grate the Parmesan and crumble the feta, then combine all the ingredients together until evenly mixed. You can do this by hand, or using the ‘pulse’ setting on a food processor. Ensure it is well combined, but don’t over process.

Line a baking tray with greaseproof paper and a little olive oil, and pre-heat the oven to 180°C fan / 200°C / gas 6. With clean and slightly damp hands, shape the mixture into sausage shapes Spread out evenly over the baking tray and brush the top of each sausage with a little oil.

Bake for about 30-40 minutes until cooked through – cut one in half to check cooked right through. Allow to cool and serve.
