In a large Dutch oven over medium heat, brown the beef until no longer pink. Once the beef is browned, drain off as much fat as possible.
Add the soup mix, diced tomatoes, frozen vegetables, and beef broth. Bring to a boil, then reduce to a simmer for 10 minutes.
Add the orzo and continue to simmer for an additional 8 minutes, or until orzo is done. Serve hot with crusty bread and butter.
