Prepare the oven and preheat it to 400° F. Also, prepare a baking tray by lining it with parchment paper.
Place chicken slices in a bowl, sprinkle seasoning powder and 1 tsp. of each ginger powder, black pepper, paprika, thyme and salt, marinade the chicken using your hand until everything is evenly coated on the chicken.
Then transfer the marinated chicken to the instant pot or pressure cooker, pour water and cook for 7 minutes or cook in a pot till tender. if using a pot, check every 5 minutes to add water if needed to avoid it from burning
Meanwhile, spread bell pepper, onion and tomato on the prepared baking tray, place in the oven and roast for 10 minutes. Save some few slices of onion to saute later.
After the chicken is fully cooked, take the chicken out of the pot and place it in the air fryer, spray with oil and air fry for 10-15 minutes. Or deep fry in a pot of oil till golden brown.
After 10 minutes, take the vegetables out of the oven and transfer them to the food processor bowl, process until smooth and everything is well blended.
Pour oil into a pot over medium heat; when oil is hot, add a few slices of onion and sauté, then add the blended pepper mix and stir until cooked through (till some of the oil floats). This will take about 10 minutes. You can also add chicken broth to adjust the thickness.
Add tomato sauce, paprika, black pepper, curry powder, ginger/garlic paste, white pepper, thyme, salt and seasoning powder. Mix until everything combines well.
Finally, add scotch bonnets, cover with a lid allow the mixture to simmer for 5 minutes. Taste to adjust.
Then carefully add air-fried or deep fried chicken and simmer for another 2 minutes, then garnish with chopped fresh parsley.
