Cut and wash catfish with hot water to remove sliminess. Rinse with clean water to ensure it's properly washed. Set aside!

Pour palm oil in a pot, add the blended tomatoes, fresh pepper, onions and ginger. Continue stirring until all moisture evaporates and it's well fried. Add some salt and seasoning cubes to taste, add required quantity of water. Cover and allow to boil a little.

When the water has boiled for few minutes, add the washed catfish into it. Ensure the catfish pieces are well placed in the pot to ensure that all of it cooks well. Cover and allow to boil until fish is cooked (let's say for about 20 mins)
