Bake chicken breast halves in a preheated oven until the juices run clear. About 30 minutes if thawed, 45 minutes if frozen.
Bring a large pot of lightly salted water to a boil. Add pasta and cook for 8 to 10 minutes or until al dente; drain.
4 minutes before the pasta is ready add frozen vegetables. When pasta is cooked, remove pasta and vegetables from heat, drain. Cut chicken into small cubes and add to the pasta-vegetable mix. Season with olive oil, pepper and salt.
