Creating Spicy Nigerian Chicken Stew is simple when you follow these easy steps:

1. Prepare the Chicken: Rinse the chicken pieces under cold water and pat dry. Season with salt, thyme, curry powder, and paprika. Set aside to marinate for about 15 minutes.

2. Heat the Oil: In a large pot, heat the vegetable oil over medium heat. Add the chopped onion and sauté until translucent.

3. Add Garlic and Ginger: Stir in the minced garlic and grated ginger, cooking for another minute until fragrant.

4. Blend the Tomatoes: In a blender, combine fresh tomatoes and Scotch bonnet peppers to create a smooth paste. Add this mixture to the pot.

5. Incorporate Tomato Paste: Stir in the tomato paste, and allow it to cook for 5-7 minutes, stirring occasionally. This helps to intensify the flavors.

6. Add the Chicken: Add the marinated chicken pieces to the pot, stirring to coat them in the sauce. Cook for about 10 minutes, allowing the chicken to brown slightly.

7. Pour in Broth: Add chicken broth or water to the pot, bringing the mixture to a boil. Reduce heat and let it simmer for 25-30 minutes, or until the chicken is cooked through.

8. Add Bell Peppers: If using, stir in the sliced bell pepper during the last 5 minutes of cooking. This adds a nice crunch and color to the stew.

9. Taste and Adjust: Taste the stew and adjust seasoning if necessary. You may want to add more salt or additional spices to suit your taste.

10. Garnish and Serve: Once cooked, remove from heat. Garnish with fresh cilantro or parsley for a pop of color.
