Italian Wedding Soup

1/2 pound extra-lean ground beef
1 egg -- lightly beaten
2 tablespoons dried bread crumbs
1 tablespoon grated Parmesan cheese
1/2 teaspoon dried basil
1/2 teaspoon onion powder
5 3/4 cups chicken broth
2 cups thinly sliced escarole or spinach
1 cup uncooked orzo pasta
1/3 cup finely chopped carrots

In medium bowl, combine meat, egg, bread crumbs, cheese, basil, and onion powder; shape into 3/4-inch balls.
In large saucepan, heat broth to boiling; stir in escarole or spinach, pasta, carrot, and meatballs. Return to boil; reduce heat to medium. Cook at slow boil for 10 minutes or until pasta is tender to bite. Stir frequently to prevent sticking. Serve with additional grated Parmesan cheese sprinkled on top.
