Sprinkle a teaspoon of salt and pepper over the chicken pieces then dredge the chicken in the flour to lightly coat.
Heat the oil in a heavy pan then add the chicken and saute for 5 minutes a side or until golden brown. Do this in 2 batches if need be.
Transfer the chicken to a plate and put the bell pepper, garlic and onion in the pan and cook for 5 minutes or until the onion is tender.
Season with salt and pepper to taste, then pour in the wine and simmer for 3 minutes or until reduced by half.
Add the tomatoes plus their juice, the oregano, capers and broth, then put the chicken back in the pan and turn in the sauce to coat well.
Bring the sauce to a simmer and simmer for half an hour or until the chicken is just cooked.
Transfer the chicken to a platter with tongs. If needed, boil the sauce for a few minutes until it thickens a bit then spoon off any excess fat from it and spoon over the chicken. Serve sprinkled with the basil.
