1 red eating apple, thickly sliced (leave the skins on)
1 tsp sage
375g puff pastry
2 tbsp Dijon mustard
Method
Heat oven to 200ºC/180 fan/gas 6.
Put the onion, sage and apple into a bowl, drizzle over a little oil and toss well.
Roll out the pastry onto a large baking tray. With a sharp knife score a border inside the pastry about a thumb’s width from the edge.
Spread the mustard over the pastry, keeping within the border, and then scatter over the sausage chunks and onion mix.
Season to taste and then cook for 20 mins until the sausage is cooked through, the onion and apple are beginning to turn golden and the pastry edges are well puffed and golden.
