In a dutch oven (or a large pot with a lid that fits), cook chicken in 1 Tbsp oil until no longer pink; remove and set aside. In the same pot, cook and stir the kielbasa, peppers, and onions in remaining oil until the onions are tender. You may have to add a little more oil. I did. Add the garlic and cook for another minute.
Stir in the broth, tomatoes, water, mustard, parsley, thyme, and Worcestershire. Bring to a boil. Reduce heat, cover & simmer for ten minutes.
Add the rice and return to a boil. Reduce heat, cover and simmer for 25 - 30 minutes or until rice is tender.
If you are using scallops, set your timer for 20 minutes instead and then stir them in and reset your timer for another ten minutes.
If you used shrimp, after the 25 - 30 minutes stir them in, then add the chicken too, cook for 2 - 4 minutes longer or until the shrimp turn pink.
If you used scallops, at the second timer stir in the chicken and cook until heated through.
