Season chicken on all sides with 1 teaspoon salt.
In a large skillet with high sides heat 2 tablespoons of the oil over medium-high. Sear the chicken skin side down for 5 minutes or until golden brown, not fully cooked. Flip and cook for 2 minutes on the other side. Transfer the chicken to a plate and set aside.
To the now empty pan, add 1 more tablespoon of oil, onions, garlic, potatoes, peppers, chickpeas and peas and saute for 10 minutes over medium heat.
Add the garlic powder, paprika, ½ teaspoon salt, broth, tamarind paste and chili sauce. Bring to a boil over medium-high heat, then reduce to a simmer (on medium-low heat).
Place the chicken drumsticks into the pan and spoon over the liquid.
Cover the pan and simmer for 30 minutes. Uncover the pan and baste the chicken with the cooking liquid and cook for another 20 minutes uncovered.
Turn off the heat and let cool for 10 minutes before serving.
