Bring a pot of water to boil over high heat and add the noodles. Cook until the noodles are tender. Drain and rinse in cold water. Place the noodles into a large bowl and toss with the sesame oil and soya sauce.
Heat a frying pan over medium-high heat. Spray with cooking spray or heat 1 tablespoon canola oil. Add the chicken and cook until it is no longer pink inside. Toss the chicken and veggies with the noodles.
Fill a container or bowl with hot water and soak one spring roll wrapper in the water until it is soft, about 15-20 seconds.
Place the softened wrapper on a cutting board and fill with about ⅓ cup of the noodle mixture. Fold in the sides of the wrapper. Fold up the bottom flap and roll. Serve with gyoza sauce.
