Preheat the oven to 220°C.
Line a baking tray with greaseproof paper.
Mix the carrot, beans, beansprouts, spring onion, red pepper, and sweet chilli sauce in a bowl.
Place one sheet of filo pastry in a diamond shape and brush with oil.
Layer a second sheet of pastry on top and brush with more oil.
Spoon one-quarter of the filling onto the corner nearest to you.
Fold the bottom corner over the filling and fold in both sides like an envelope.
Brush with oil and roll up into a sausage shape.
Repeat the process for the remaining three spring rolls.
Bake for 15 to 20 minutes until golden-brown and crisp.
