Prepare pasta according to package directions.

While pasta is cooking, pour Alfredo into a medium saucepan. Pour the chicken broth into the jar and replace the lid. Shake well to get all of the excess sauce out. Stir the broth mixture into the saucepan with the sauce.

Stir in the tomatoes and basil and cook over medium-low heat until mixture is thoroughly heated. Add the parmesan and stir continuously until melted.

Add the pasta to sauce and coat evenly. Serve warm.
