Prepare each rice paper wrapper by dipping in warm water to soften. Lay flat and place some noodles, carrot, spring onion, cucumber and ¼ can John West Tuna along the centre. Fold ends of rice paper over and roll to secure, adding herbs towards the end of rolling. This will yield translucent herbs in the rolls. Repeat with remaining wrappers and ingredients.
Combine sweet chilli sauce, soy sauce and sesame oil in a small bowl. Serve dipping sauce and lime wedges with rice paper rolls.
The rice paper rolls can be made a few hours ahead of time and stored covered in the refrigerator.
