In cooker, heat olive oil then chicken, brown for approximately 5 minutes, then add rest of ingredients. Close the lid and bring to pressure, lower heat and cook for the suggested time. My pressure cooker says on position 1, 21 minutes. On position 2, 12 minutes. Release the pressure and remove the lid.
If you are not using a pressure cooker then simmer for approximately 1 to 1 1/2 hours. (Watch your amount of fluids and add broth as needed).
Serve over polenta (follow the directions on the polenta package). Enjoy!
