Instructions

1. Preheat the oven to 180°C and get your baking tray ready with a sheet of greaseproof paper.

2. Sausage transformation time - Remove those sausage skins and pop the meat into a large bowl. Add your diced onion and wholegrain mustard, then mash it all together with a fork until well combined.

3. Pastry fun - Unroll the puff pastry and, using a sharp knife, cut it in half lengthways.

4. Fill 'em up - Spoon the sausage mixture down the middle of each pastry half.

5. Roll and flip - Roll the pastry over the sausage filling and flip it so the seam is underneath.

6. Slice and dice - Cut each roll into 8 pieces, giving you 16 delightful mini rolls.

7. Arrange and prepare - Place the rolls on the baking tray with the seam side down.

8. Egg wash magic - Beat an egg in a small bowl, then brush it over each sausage roll. Sprinkle any extra toppings you like.

9. Bake to perfection - Pop them in the centre of the preheated oven for 18-20 minutes, until the pastry is golden brown and irresistible.

10. Cool and enjoy -  Let the sausage rolls cool slightly on the tray before serving. 

These tasty treats are perfect for any lunch box or quick snack!
