Toast the sesame seeds in a skillet over medium-high heat until lightly golden, about 3-5 minutes.

In a large pot, boil lightly salted water and add the bow tie pasta. Cook for 8-10 minutes until al dente, then drain and rinse with cold water.

In a jar, combine vegetable oil, soy sauce, rice vinegar, sesame oil, sugar, toasted sesame seeds, ginger, and pepper. Shake well until sugar is dissolved.

Pour the dressing over the cooled pasta and toss to coat. Mix in the chicken, cilantro, and green onions.
