Soak the dry-salted fish in water for an hour, remove it from the water, take the bones and fins out, and cut them into pieces. Boil water and use it to rinse the dry-salted fish. This removes the excess salt, so the poisson salé is not salty. You can also soften it in hot water for a few minutes.
Wash the Poisson Salé again in cold water to remove excess salt.
Pour oil into a skillet and bring to a boil for 2 minutes.
Spice the Poisson Salé and fry it in the hot oil for a few minutes.
In a separate pot, bring the oil to a boil and sauté the onions.
Add all the vegetables, including the hot pepper, stir, and cover to cook for 5 minutes.
Mix the spinach in the sauce and allow it to steam for a few minutes.
Add the Poisson Salé to the sauce and stir.
Add the vegetable broth and additional whole habanero pepper.
Let the sauce simmer for a few minutes, then turn off the fire.
Serve with your favorite rice or boiled yam.
