Cut chicken into thin strips and in a large saucepan, sauté in coconut oil for 2-3 minutes, or until chicken turns white.
Add coconut milk and water and bring to a boil. Reduce heat and add ginger, fish sauce, lime juice, cayenne, sugar, and turmeric.
Simmer until the chicken is done, about 10 minutes. Adjust seasoning adding more cayenne if necessary.
Sprinkle with fresh cilantro and sliced green onions.
