Preheat oven at 200°C fan/180°C/ Gas 6/400°F. Lightly, grease a baking tray with vegetable or sunflower oil. Add the tilapia pieces to the tray and drizzle oil on top of each piece. Bake for 1 hour and 30 minutes or until dry and brown in colour.
Meanwhile, add 1 can of plum tomato, 1 large chopped onion, 2-3 scotch bonnets, 2 chopped red bell peppers, and pulse for 2-3 times. The consistency should not be smooth.
Once, the fish is ready remove it from the oven and set aside. Then, heat vegetable oil in a pan, add 1/2 of a sliced onion then pour in the tomato mixture and cook for 10-15 minutes on a medium heat.
Next, season the sauce with 1 Knorr chicken stock seasoning cube, salt to taste, 2 tsp of tomato puree (optional) and stir. Then, cook on a low heat for 15-20 minutes.
Then, add the grilled tilapia pieces to the sauce and cover each piece with the tomato sauce. Cook for another 10 minutes.
Finally, add 1/2 of a thinly sliced onion, 1 thinly sliced red bell pepper and leave to simmer for 5-7 minutes. Garnish with fresh green herbs of your choice and enjoy!
