Cook broccoli in boiling, salted water: drain. (If using frozen broccoli you don't need to cook it first.) Melt butter; blend in flour, salt and dash pepper. Add chicken broth all at once; cook and stir til mixture thickens and bubbles. Stir in cream and wine.
Place broccoli crosswise in 12 x 7.5 x 2 inch baking dish. Add half the sauce. Top with chicken pieces. To remaining sauce, add Parmesan cheese; pour over chicken; sprinkle with extra cheese. Bake at 350 for 20 minutes or until heated. Then broil just til sauce is golden. Makes 6 to 8 servings.
