Marinate the chicken thigh meat in the pineapple juice for 30 minutes.
In a pot, sautee onions and garlic powder in a little oil until onions are translucent. Add chicken cubes and chicken thighs and brown. Keep the marinade.
When the chicken thighs are browned, add the marinade, carrots, and enough water to just barely cover the meat. Allow to boil for 20 minutes.
Add the sugar and stir through. While stirring, pour the evaporated milk, stirring all the while. Allow to bubble again, and add the pineapple chunks.
Simmer for another 10 minutes, stirring frequently. Serve with white steamed rice.
