Top Tips
For a more appetising color, fry the sausages in a pan for 1-2 minutes on high heat. They will become brown once seared - take them off the pan, remove any excess fat if you prefer, before adding the chopped vegetables.
For best results, keep the slow cooker's lid shut most of the time. This will help keep the temperature and the cooking process going.
Keep an eye on the levels of liquid in the pan, and add more if you cannot see any sauce, or if it seems dry. This will help prevent it from drying out and burning.
