Preheat oven to 220°C/200°C (fan-forced) and line 2 baking trays with baking paper

Heat oil in a medium frying pan over medium heat. Add onion, garlic and fennel seeds. Cook, stirring occasionally, until tender. Cool

Mix cooled onion mixture, mince, carrot, tomato sauce, breadcrumbs, cheese and 1 egg together in a large bowl until well combined. Season with salt and pepper

Cut pastry sheets in half. Shape ½ cup of meat mixture into logs along the centre of each piece of pastry, brush one edge with remaining beaten egg and firmly roll pastry over the meat, pressing to close the edge. Cut each length into 4 sausage rolls

Arrange sausage rolls, seam side down, onto baking trays. Brush with more egg and sprinkle with sesame seeds. Bake 25-30 minutes, or until golden brown and cooked through. Serve warm with extra tomato sauce
