Break pasta in half so that it fits horizontally in pot. Place over cooked chicken. Place all vegetables, seasonings, and cubed cheese over pasta. Cover with water and bring to boil over high heat. Boil, stirring occasionally, until pasta is cooked and water has almost evaporated, about 10-12 minutes.
3 Remove from heat and let stand until remaining water has fully absorbed and dish is creamy (rather than runny).
4 Garnish with chives and Parmesan.
