In large saucepan over medium heat, cook beef until it is no longer pink; drain. Stir in the corn, tomatoes, broth, onion, garlic and seasonings. Bring to a boil. Reduce heat; cover and simmer for 30-45 mins.
For dumplings, combine flour, cornmeal, baking powder and salt in a large bowl. In another large bowl, beat egg; stir in milk, corn cheese and parsley. Stir into dry ingredients just until moistened.
Drop by tablespoon onto the simmering soup. Cover and simmer for 15 minutes or until a toothpick inserted in a dumpling comes out clean. (do not lift cover until end of the 15 minutes of simmering.)
