STEP 1: Clean and cut the Abo fish into pieces. Marinate with a bit of salt and a crushed seasoning cube, and set aside for 30 minutes.
STEP 2: Blend the tomatoes, peppers, and half of the onion into a smooth mixture. Set aside.
STEP 3: Heat oil in a large pot over medium heat. Add sliced onion and fry until slightly golden.
STEP 4: Stir in the tomato paste and fry for 3 to 5 minutes to reduce acidity.
STEP 5: Add the blended tomato mixture and cook uncovered on medium heat for 20–30 minutes until the oil separates.
STEP 6: Season with salt and remaining seasoning cubes. Stir thoroughly.
STEP 7: Add the marinated Abo fish and reduce heat to low. Allow it to simmer gently for 10 to 15 minutes so the fish cooks without breaking apart.
STEP 8: Taste and adjust seasoning if needed. Serve hot with rice, boiled yam, or fried plantain.
