Chili's Chicken Enchilada Soup

1. In large pot, combine oil, chicken base, onion, and spices. Saute until onions are soft and clear (about 5 minutes). 2. In a mixing bowl, combine Masa Harina with 1 quart water. Stir until all lumps dissolve. 3. Add Masa Harina "rue" to sautéed onions bring to a boil. Once mixture starts to bubble, continue cooking 2-3 minutes, stirring constantly. This will eliminate any raw taste from Masa Harina. 4. Add tomatoes and remaining 3 quarts water to pot. Let mixture return to boil stirring occasionally. 5. Add American cheese (or Velveeta) to soup. Cook, stirring occasionally, until cheese melts. 6. Add chicken; heat through.
