Heat 1 tsp oil in a suitable pan, fry the sausages and sliced onions until browned.
Place into a slow cooker (if using) with all remaining ingredients and combine well.
Cook 2 hours on high or 4 hours on low.
More water can be added as required. Can be thickened with a little cornflour.
A perfect complement when served with steamed vegetables, rice, salad, or even mashed potatoes. Great with slices of freshly buttered bread to soak up the delicious sauce.
Tips: Can also be cooked on stove top or in oven using cast iron pot or casserole dish.
