Preheat the oven to 180 C. Prepare a baking tray with greaseproof paper. Remove pastry from the freezer, and set on the countertop to soften. (If using homemade, prepare this first).
Place the pork, onion, garlic and grated veg in a food processor. Blitz for 20-30 seconds.
Mix the herbs and spices to the flour/breadcrumbs and mix. Add to the pork mix and blend until combined. Transfer to a large bowl, and cover. Place in the fridge for 10 minutes
Meanwhile, prepare the pastry by rolling and dividing into 2 rectangles.
Remove the pork mix from the fridge. Divide in half, and spread half the mix onto each pastry strip. Fold the pastry into a roll using a fork to press the edges together.*
*If freezing, cut each roll into 8, and place in freezer using a pot from the Large Mixed Set
Brush with beaten egg. Slice each pastry strip into 8. Bake for 25-35 minutes, until golden and cooked through. Allow to cool before serving.
