Peel and core your apple, before chopping into slices (it doesn't really matter how big or small these are, as they will be later blitzed in a food processor). Add into the food processor, along with your chopped garlic clove and sliced bacon rashers.
Skin your sausages by making a slight incision on one end and squeezing the meat out from the other, straight into the food processor along with the apple, bacon and garlic. Whizz until all of the ingredients form a paste.
Meanwhile, roll out your pastry into 5-6 rectangles on a lightly floured surface. Spoon your sausage paste onto each rectangle and roll up, pinching the ends together so no meat falls out.
Place your sausage rolls on a baking tray. Brush with egg, and scatter your sesame seeds on top.
Bake for 20 to 25 minutes, until golden brown.
Great for party nibbles - once you have rolled your sausage rolls, cut them into mini bites.
