Peel your potatoes and dice them and load the potatoes into the slow cooker with half the butter or margarine, salt, pepper, and mixed herbs. Allow to slow cook for 90 minutes to create soft mashed potatoes. After 90 minutes put the potatoes to one side in a suitable bowl and add the milk and other half of the butter.

Move the slow cooker to the stovetop to sauté the sausages with a little extra virgin olive oil and sauté until you start to see colour on the sausages.

Add the other slow cooker ingredients to the sausages and place on slow cook on high for 2.5 hours. After an hour though give it a stir.

Whilst the slow cooker is back on, mash your potatoes and then put to one side for later.

When the slow cooker is done, load the sausages onto dinner plates and then stir in a heaped tablespoon of the mash to make a thick onion gravy.

Pour the onion gravy over the sausages and reheat the mashed potatoes for 2 minutes in the microwave. Then serve together your sausages, onion gravy and mashed potatoes.
