A hearty soup that is perfect for lunch or dinner. I often make this soup for supper, accompanied by a salad and crusty bread. It's also a good recipe to use up extra chicken and the cilantro I always have left over from other recipes.
In large saucepan, combine chicken, broth, cilantro, green onions, celery, garlic and cumin. Bring to a boil. Reduce heat to low; cover and simmer for 15-20 minutes, or until chicken is tender.
Pour mixture into a blender and add flour. Cover and blend, starting at low speed, until smooth.
Pour mixture back into the saucepan. Cook over medium heat, stirring constantly, until mixture comes to a boil and thickens. Remove from heat. Gradually stir in evaporated milk. Reheat just to serving temperature. DO NOT BOIL. Season with pepper to taste. Garnish as desired.
