Blend the onion, mixed veggies, soy sauce, garlic, salt/pepper and eggs together in blender. Add this to the mince and mix well. Then add enough breadcrumbs to make mixture firm enough for filling.
Roll out 2 long rolls of mixture across each sheet of pastry, cut through the centre of the pastry and roll up – moistening the edges with milk to help stick. Cut each roll into 4 party sausage rolls (or to the size you want.)
Put on baking trays (seal side down) lined with baking paper so they don’t stick. Brush each sausage roll with a little water then sprinkle with Italian herbs. Bake in preheated oven for around 30 to 40 minutes or until golden brown – about 30 minutes.
