Step 1Preheat oven to 180°C. Line a large baking tray with baking paper.
Step 2Place mince in a large mixing bowl with zucchini, carrot, onion, paprika and oregano. Add sweet chilli sauce, soy sauce, vinegar and egg, and combine. Add oats and knead mixture together well using clean, wet hands.
Step 3Cut the sheets of puff pastry in half. Place a thick line of the mince filling along the middle of the length of one pastry sheet half; dampen the edges with a little water, then roll it up.
Step 4Cut the length into five mini sausage rolls and place rolls on prepared tray. Repeat with remaining filling and pastry sheets to make 30 sausage rolls.
Step 5Brush sausage rolls with milk and lightly spray with olive oil. Using a sharp knife, cut a small slit in the top of each roll. Bake for 15 minutes, or until golden. Allow sausage rolls to cool on tray slightly, then serve warm.
