2 10 oz. cans of Fire-Roasted Rotel (diced tomatoes and green chiles), drained
1 14.5 oz. can of kidney beans, rinsed and drained
1 cup fine ground yellow cornmeal
3/4 cup all-purpose flour
1 TBS sugar
3/4 teaspoon baking soda
1/2 tsp salt
1 large egg, lightly beaten.
2/3 cup buttermilk
2 TBS butter, melted
In a 10-inch cast iron skillet over medium heat, season the ground beef with salt and pepper and brown, breaking into small crumbles with a spatula as it cooks. Remove the beef to a plate and set aside, reserving a couple of teaspoons of the grease in the pan.
Add the chopped onions to the pan and cook until translucent and fragrant, then add the minced garlic and cook for a couple minutes more.
Return the beef to the skillet and add chili powder, cumin, cinnamon, chicken broth, Rotel, and beans. Reduce heat to low and allow to simmer until the liquid reduces a bit and starts to thicken (this could take as long as 20-30 minutes)
While the chili is simmering, preheat your oven to 400F. In a large bowl, mix the cornmeal, flour, sugar, baking soda, and salt. Stir in the beaten egg and then stream in the buttermilk while mixing, stopping when the mixture is just combined.
Once the oven is preheated and the chili has thickened, taste the chili and adjust seasonings to your preference. Pour the cornbread batter over to the top of the chili and bake on the middle rack for 15-17 minutes or until the cornbread is golden, set, and springs back when touched.
Remove the skillet from the oven and brush the top with the melted butter.
Serve hot with sour cream and cheddar cheese, if desired.
