Heat an oven to 180 degrees. Prick the sweet potatoe all over and place in the oven for about 40 minutes. To make the stuffing add a tin of black bins and corn to a pot and heat slowly. Add half a tin of chopped tomatoes to give it a little moisture along with the chipolte or other chili. Cook on a medium heat for about 20 minutes. Slice the sweet potatoe and add the mix on top.
