Heat the olive oil, in a large skillet, over medium high heat. Add the chicken and saute for 2 minutes a side to add some color. Remove the chicken to a plate.
Add the bell pepper, carrot, celery and garlic to the skillet and saute, stirring continuously, for about 2 minutes or until the vegetables begin to get tender. Add the white wine and evaporate. Add the tomatoes, return the chicken on top. Cover and cook over low heat for 5 to 8 minutes or until the chicken is cooked through.
Remove the chicken and set over the warm rice salad. Adjust seasoning of the pan sauce and spoon over the top.
