Then, add onion, celery, and carrots to mixture and saute for another 5 minutes, or until slightly translucent. Add water and bring to a boil. Lower heat to a simmer, and cook for 20 to 25 minutes. Strain. Place strained mixture over low heat in a saucepan. Add daikon, cilantro and tomato and cook just until ingredients are heated through. Reserve.

On medium high heat saute watercress and Manoa lettuce in olive oil for 5 to 10 seconds, just to wilt. Place greens in the middle of a plate and top with sauteed moi. Pour the shrimp nage around fish and greens.
