Cook pasta according to package directions. Drain, rinse, and place in a large bowl. Toss pasta with sesame oil.
Meanwhile, in a separate bowl, stir together broth, soy sauce, oyster sauce, brown sugar, and cornstarch. Set aside.
Heat a large skillet or a wok over medium-high heat and coat with vegetable oil or spray with cooking spray. Add garlic and chicken and stir for about 3 minutes, or until no longer pink. Remove chicken from skillet and cover with foil to keep warm.
Add cabbage, stir-fry vegetable blend, and bamboo shoots to the skillet and stir-fry for 3-5 minutes (or until cabbage is wilted and vegetables are tender).
Add broth mixture, cooked pasta, and cooked chicken back to the skillet with the vegetables. Stir-fry for 2 more minutes, or until sauce thickens. Serve.
