Expert Tips and Notes
  1. For keto-friendly South Beach diet, leave out carrots and select stewed tomatoes with minimal sweetener. See notes above for alternative ways to thicken sauce if desired.
  2. Browning chicken is optional. It seals in moisture and adds to the appearance of the chicken.
  3. To make ahead and freeze: Add all of the ingredients to plastic bag that seals (double bag) or a container with a lid. Remove to the refrigerator to defrost and cook normally in the slow cooker.
