Really easy- mix mince, bacon, onion carrot, zuchini and garlic together in large bowl. Spoon mixture onto puff pastry sheet, spread and then roll almost to the end.
Brush some milk on the end of sheet and roll the end to seal. Trim both ends, slice in half and place on a prepared baking tray.
Repeat until mixture is used up, brush rolls with milk and place in oven at 160*C for 45 to 60 mins. Mine took 60 mins on low fan.
