Cook macaroni according to package directions, but in the last 3 minutes of cooking add the broccoli to the cooking water and stir. Drain and set aside.
Melt the butter in a large saucepan over medium heat. Whisk in the flour, stirring for 1 minute until the flour is lightly toasted, then gradually add the milk and dressing at the same time, stirring constantly until the sauce is smooth and has thickened.
Remove from the heat and add the cheese, stirring until completely melted and incorporated.
In a large bowl, combine the pasta and broccoli with cheese sauce, stirring until well-coated. Serve immediately.
