As with any of our recipes, carb counts, calorie counts and nutritional information varies greatly. As a result, your nutritional content depends on which products you choose to use when cooking this dish. The auto-calculation is just an automated estimate and should NOT be used for specific dietary needs.
All slow cookers cook differently, so cooking times are always a basic guideline. Recipes should always be tested first in your own slow cooker and time adjusted as needed.
