Add some veggies, such as 1 cup frozen peas or broccoli, to the skillet for the last 5 minutes or so of cooking time. Heat until vegetables are cooked.
There are so many great packaged rice mixes on the market these days. Try a rice pilaf or other rice mix seasoned with herbs. Start it when you start cooking the chicken dish, and both will be ready at the same time.
The chicken and sauce is also delicious served over pasta.
