Preheat your oven to 200°C (400°F) and line a baking tray with parchment paper.
In a large bowl, combine the ground meat, onion, garlic, carrot, Worcestershire sauce, tomato paste, breadcrumbs, 1 egg, parsley, and dried herbs. Season with salt and pepper. Mix thoroughly until well combined.
Cut each pastry sheet in half to form rectangles.
Divide the meat mixture into 4 portions and form each portion into a long sausage shape along the long edge of each pastry rectangle.
Beat the extra egg and brush along the opposite edge of the pastry.
Roll the pastry to enclose the filling, with the seam on the bottom.
Cut each roll into 4-5 pieces (about 5cm each). Make small slits on top of each roll.
Place the rolls on the prepared baking tray. Brush with egg wash and sprinkle with sesame or poppy seeds if using.
Bake for 25-30 minutes until the pastry is golden brown and the meat is cooked through.
Allow to cool slightly before serving with tomato sauce.
