In a medium skillet, cook sausage until brown and no longer pink in center; drain on paper towels. Slice sausage into bite-size pieces; set aside.
In a 3-quart saucepan, combine water, undrained tomatoes, cabbage, onion, green pepper, bouillon granules, basil, and pepper. Bring to boiling; reduce heat. Simmer the mixture, uncovered, for 15 minutes.
Stir in tortellini, zucchini, and sausage. Return to boiling; reduce heat. Cook, uncovered, about 5minutes or until pasta is tender, stirring occasionally. Makes 6 servings.
Trim some fat from this soup by using reduced-fat sausage links and tortellini.
