Normally I don't see the point in embellishing something so perfect as cornbread with additional crap, particularly meat, but this is a very popular variation where I'm from. It doesn't have a name that I am aware of so I will name it...
novasoy's Hammy Cornbread
2 boxes of sweet yellow cornbread mix
2 cans, yellow sweet whole corn, drained
2 cups, shredded smoked or country ham
.5 cup, diced yellow onion
other ingredients listed on cornbread box (milk, eggs, oil, etc.)
You see, what you are basically doing is making a double batch of cornbread with some ham and onions in it. Coat the bottom of a large cast iron skillet with cooking spray. Preheat your oven to 375°. In a large mixing bowl, mix all ingredients together, and then pour into the skillet. Place skillet into the oven. It should take about 40 minutes to bake, but you should test it with a toothpick every 10 minutes or so so it doesn't overcook. When the toothpick comes out clean, you're ready to eat!
This recipe goes great with a pot of beans, as the Cab Calloway/Louis Jordan song "Beans and Cornbread" attests, or try it with some chili.
