Finely slice the onion, grate the carrots, chop the coriander and shred the cabbage. Preheat the oven to 180 degrees
Combine the onion, carrot and coriander and mix in a large bowl with the chicken mince. Season well.
Break an egg and to create an egg wash for the pastry, lay the chicken mix onto the pastry roll evenly, in a tube form, leaving approximately 1cm from the shortest surface.
Brush the pastry with the egg was on the longer side and fold the pastry over – keep firm while rolling to make a tight log.
Cut into serve sizes of 12 cm, or smaller for a snackable serving. Give the roll a number of fork pricks and brush the outside of the rolls with the egg wash.
Bake in a moderate oven at 180 degrees until golden brown and cooked through (20-25, depending on size).
