Pre-heat the oven to 200C (430F) fan-forced and line two baking trays with baking paper.
Lay the sheets of puff pastry out on the bench and either slice in half down the middle for rolls or leave whole for scrolls.
Combine all the ingredients in a large bowl and squelch them together.
For sausage rolls, make a sausage of mince mixture down the centre of the half slice of pastry then wrap to enclose the filling then slice into the desired thickness then place them on the lined baking trays seam-side down.
For scrolls, spread a sheet of pastry with mixture about 5mm thick leaving a small border of pastry at the top and bottom then roll it up into a log. Use a serrated knife to slice up pieces about 2-3cm thick then place them on the lined baking trays.
Brush the sausage rolls with milk and sprinkle with sesame seeds.
Bake for 25-30 minutes for scrolls and a little longer for sausage rolls.
