Heat vegetable oil in a skillet over medium-high heat. Cook and stir onion, garlic, curry powder, and thyme until onion is soft and golden - about 7 minutes. Stir in seasoned chicken and cook until chicken is lightly browned, about 5 minutes.

Pour water into the skillet and reduce heat to low. Cover and simmer for 15 minutes and continue until chicken is no longer pink at the center - an additional 15 minutes. Season with salt.

Serve with steamed rice.
