A dish that I have been making for company a lot recently that has not yet failed to have people go back for seconds (even the non-foodies and skinny people!), is chili served over sweet potato. I've served it both as a turkey chili and as a vegetarian chili. I always get comments about how good the spiciness of the chili (and I actually only make it medium spicy) tastes with the sweetness of the sweet potato.
It made me wonder about what other dishes are out there, that combine spicy and sweet. Do you have favorites? Especially wanted are easy to make ones!
