Blend the onion and spices and mix with the meat.
Place in your SC and break up so its not sitting flat on the bottom.
Top with the sweet potatoes .
Blend the tomato paste and tinned tomatoes together and pour over the potatoes.. ( I also added more chilli to the tomato mixture) .
Cook on low 8-10 hours until the sweet potato is tender. ( Cook on high until tender if in a hurry).
Serve in bowls and top with coriander , avocado , sour cream , grated cheese or Greek yoghurt or combinations of everything.
