Rinse the fish thoroughly, then marinate with fish sauce, chili powder, onion powder, and a pinch of seasoning.

In a pot, caramelize a pinch of sugar with a little water to make a brown sauce, then add the marinated fish and pour in enough hot water to just cover the fish.

Simmer on low heat for about 15 minutes until the fish is just cooked. Dice the bell pepper and add it to the pot.

Add a little syrup, then continue to simmer for another 30 minutes until done.
