Add turmeric, coriander powder or Garam Masala, black pepper, salt, chili powder, chat masala and roasted red pepper, mix well, the spices should coat the chicken pieces. Stir and cook covered on low to medium heat until chicken is fully cooked. About 8-10 minutes. Taste and adjust seasoning. If you're left with some liquid, boil the curry so the water evaporates and the curry thickens. You don't want a lot of sauce, the sauce should be just right to coat the chicken pieces.
