Heat 2 tablespoons of the cooking oil in a pot over medium heat. Add the onion, saute until softened, about 5-7 minutes. Add the garlic and saute for 1 minute. Add the chicken, increase heat to medium-high and saute until no longer pink.
Add the curry powder, oregano, and red crushed pepper. Stir well. Add the chicken broth and crushed tomatoes. Cover the pot and bring to a boil. Then reduce heat to medium-low and simmer covered for 10-12 minutes.
Add the diced tomatoes, black beans, and salt to taste. Cook covered over medium-low heat until chicken is cooked through, about 40 minutes. Add the capers and cook for 10 more minutes. Taste and adjust seasonings. Serve with rice or bread.
