Spray inside the slow cooker pot with cooking spray or lightly grease.
Transfer the drained part cooked beans to the slow cooker and add the carrots, onions, herbs and pepper.
Add approx 1 litre of boiling water or more to cover the vegetables and beans.
Add meat and push in amongst the beans and veg.
Replace lid and cook on high for 1 hour – DO NOT OMIT THIS. Check the water level and top up if necessary.
Turn slow cooker to low and cook for a minimum of 8 hours or keep on high for a further 5 hours. Bean Jar can be cooked for up to 24 hours, I usually cook mine for 16 hours.
Shred the meat and return to the Bean Jar, stir and add salt and extra pepper to taste.
Optional, sprinkle with freshly chopped parsley and serve with crusty bread and Guernsey butter.
