Cool Chicken and Noodle Salad

Cook the noodles according to package directions. Rinse under cold water to cool, then toss with the sesame oil (if using). Meanwhile, in a large bowl, whisk together the lime juice, brown sugar, chili (if using), 1/2 teaspoon salt and 1/2 teaspoon pepper. Add the apple, cucumber, and scallions to the lime juice mixture and toss to coat. Slice or shred the chicken, discarding the bones. Add to the apple-cucumber mixture and toss to combine. Add the noodles and mint and toss again.
