If you haven't already, soak the saltfish in water overnight, changing the water a few times to remove excess salt. Drain and flake into bite-sized pieces.
Heat vegetable oil in a large skillet or pot over medium heat.
Add the chopped onion, minced garlic, bell pepper, and Scotch bonnet peppers. Sauté until the onions are soft and translucent, about 5 minutes.
Stir in the chopped tomatoes and cook for another 2 minutes.
Add the flaked saltfish to the skillet. Stir in thyme, paprika, and ground allspice. Cook for a few minutes until the saltfish is heated through.
Add the diced potatoes and cook for about 10 minutes, or until they start to soften.
Stir in the green peas and cook for an additional 5 minutes until all vegetables are tender.
Season with salt and black pepper to taste (be cautious with the salt as the saltfish can be quite salty).
Stir in the chopped fresh parsley or cilantro.
Enjoy your meal!
