Place the butter in a small frying pan and melt.

Mix together in a small bowl the breadcrumbs, cooking apple, cinnamon and walnuts. Add half the melted butter and mix together well.

Take two sheets of the fillo pastry and place on a board. At the end nearest to you place one sausage and a large spoonful of the mixture onto the edge of the pastry.

Using the remaining melted butter, brush the edges of the pastry. Roll up – if the pastry splits just brush with a little more butter.

Take the ‘sausage’ shape and gently bend into a crescent shape, twist off the very ends of the pastry and place on a baking sheet. Brush all over with butter. Repeat using the remaining sausage, pastry, etc.

Place in a preheated oven and cook for about 30 minutes until golden brown.
