Remove the sausage meat from the tube and work it a little in a bowl until you have a more workable mix. You can add some additional seasoning here if your sausage meat is not already seasoned.
Lay out your sheet of puff pastry.
Place the sausage meat on the puff pastry and then roll over onto itself to cover the sausage meat. I find that I can make two batches of sausage rolls if I go widthways along the pastry, near the bottom and near the top.
Crack the egg into a bowl and whisk well.
Brush the beaten off over the top of the rolled pastry with the sausage meat inside.
Sprinkle the sesame seeds over the top of the brushed pastry.
Cut the sausage rolls to your desired size. I was able to get 22 mini sausage rolls from the mix, ideal for serving up at a party or when you have guests dropping in.
Air fry at 180C (355F) for 8 minutes, or until golden brown.
Serve with tomato ketchup or your choice of dipping sauce.
