In a medium saucepan of boiling salted water, cook macaroni until al dente (slightly firm) following package instructions; drain.
In the same saucepan bring the broth to a simmer over medium heat. Add the vegetables; cook 5 minutes. Add the sausage and macaroni and cook just until heated through. Remove from heat; stir in basil. Transfer to a thermos (or two); divide Parmesan and wrap separately. At lunchtime, add Parmesan and serve with a wedge of corn bread, if desired.
