Next time you're planning on making chili and cornbread. Try this: after making your chili, put it in a baking dish, mix up your corn bread and smooth it over the top. Bake however long the cornbread needs. I would only put it over chili that is pretty thick. I think if there's too much liquid in your chili the cornbread mix might soak down into it.
I used Trader Joe's cornbread mix here, and it baked up nicely on top of the chili.
It would be yummy over black beans too.
