Place chicken in a large pot with water, add salt and bring to a boil. Reduce heat to a low simmer and cook chicken until tender, about 45 minutes.

Heat oven to 350°F. Grease 9-by-13-inch baking dish with cooking spray.
In baking dish, spread rice in an even layer. Layer broccoli over rice. In a large bowl, mix soup, sour cream, mayonnaise, lemon juice, shredded chicken, half the shredded cheese, and salt and pepper to taste. Pour mixture over broccoli and top with remaining shredded cheese. Bake for 40 minutes. Let stand for 5 minutes before serving. Makes 10 servings.
