Italian Chicken Casserole

Crumble sausage into a skillet; add onion and celery. Cook over medium heat until meat is no longer pink; drain and set aside. Sprinkle chicken with paprika. In the same skillet, cook chicken in oil for 2-3 minutes on each side or until chicken juices run clear; remove and set aside. Return sausage mixture to the skillet. Add the broth, bouillon, garlic, rice, salt and pepper. Bring to a boil. Reduce heat; cover and simmer for 15 minutes. Add chicken and mushrooms; cook 5 minutes longer or until rice is done and chicken is heated through.
