Heat olive oil over med heat in a large skillet.Add sausage and cook until sausage is almost cooked and takes on a golden color.Remove sausage from pan and set aside.In the same skillet add the cubed chicken and cook until chicken is cooked. This will only take several minutes. Make sure to brown chicken on all sides.Remove chicken from pan and set aside.Add rice to skillet and stir continuously for 1-2 minutes.Stir in chicken broth.Cover and reduce heat to a simmer.Allow to cook for approximately 8 minutes.Add chicken, sausage, salsa and parsley.Cover and allow to cook until most of the liquid is absorbed by the rice and the rice is tender, approximately another 4 minutes. If you are adding shrimp, I would add the shrimp into the skillet at this time.You may need to stir from time to time to make certain that the rice is not sticking to the skillet.When serving add the fresh tomato to the top of each portion. You may also choose to add some additional fresh parsley when servicing as well.
