In a large nonstick skillet, heat the oil. Saute the chicken, stirring
constantly, 4 minutes. Add the scallions and garlic; cook, stirring frequently,
until the chicken is cooked through, 2-4 minutes.
Stir in the tomatoes, parsley, capers, vinegar and rosemary. Reduce the heat and
simmer until the liquid evaporates, about 10 minutes. Serve the chicken mixture
over the noodles.
