In a bowl, combine the beef-flavored rice vermicelli mix, ground beef, and beaten egg, reserving the seasoning packet from the mix.

Form the mixture into one-inch meatballs.

In a skillet over medium heat, cook the meatballs, turning occasionally, until browned on all sides; drain any excess fat.

In a bowl, combine the reserved seasoning packet and water; pour over the meatballs.

Cover the skillet and simmer for 30 minutes or until the sauce is thickened, and the meatballs are no longer pink in the center.
