1Combine ground beef, egg, bread crumbs, Parmesan cheese, basil, and onion powder in a bowl.
3Heat broth in a large pot over medium-high heat until boiling. Stir in escarole, orzo, carrot, and meatballs and return to boil. Reduce heat to medium and cook at slow boil, stirring frequently to prevent sticking, until pasta is tender yet firm to the bite, about 10 minutes.
