This recipe requires a large skillet with a lid. An electric fry pan works well to prepare this dish.
Melt the margarine over medium high heat in the large skillet. Add the chicken and cook about 2 minutes on each side or until browned. Remove the browned chicken from the skillet and keep it warm.
Use the same skillet to prepare the Rice-A-Roni Spanish Rice. Sauté the rice-vermicelli mix over medium heat until the vermicelli is golden brown, stirring frequently.
Slowly stir in 2 cups water, contents of seasoning packet, and the tomatoes. Place the browned chicken over the rice mixture. Bring the mixture to a boil.
Cover and reduce the heat to low. Simmer 15 minutes. Add the broccoli.
Cover and simmer 5 more minutes or until liquid is absorbed and chicken is no longer pink inside. Sprinkle with the cheese and serve.
