A true comfort meal! Use a good-quality sausage without nitrites.
Place sausages, peppers and onions in slow cooker.
Pour sauce on top.
Place lid on slow cooker and cook for 4 hours on high or 6-8 hours on low, depending on how quickly your slow cooker cooks. The peppers should be soft.
Serve over cooked whole wheat pasta and top with grated parmesan cheese if you'd like!
I have made this recipe with both cooked and raw sausages and it comes out great either way. If you use raw sausages, you can saute them in oil for a few minutes first to brown them before adding them to the slow cooker. However, if you are short on time, this step is not necessary and the sausages can just be added raw to the slow cooker.
