Since our family made big changes to our diet over a year ago, I've been wanting to find a good recipe for sweet potato chili. I've tried at least two different recipes and neither was very good. I recently had some sweet potato chili at LeAnne's house, though, that was perfect! She got this recipe from a friend, passed it on to me, and I tinkered just a bit with it to suit my family's preferences. It's a keeper and will be on regular rotation at our house. The pineapple and cinnamon, I think, really make the dish.
