Preheat oven to 425º. Place 8-10" castiron skillet in the oven to preheat.
Brown ground beef in a skillet over med-high heat. Add Worchestershire sauce, jalapeno (or chiles), onion, salt, and pepper to taste. Drain.
In a medium bowl, mix eggs, 1/2 can cream-style corn, milk, cornbread mix. Mix well to combine.
Remove cast iron skillet from oven. Place butter in the skillet and let melt. Brush butter around the inside of the skillet. Layer ingredients in this order:
1. 1/2 cornbread batter
2. meat mixture
3. 4 slices cheese
4. remaining 1/2 can of corn
5. remaining 1/2 of batter
Bake for 25-30 minutes. Let cool 10-15 minutes before serving. It is very important to let it cool prior to cutting and serving in order for the cornbread to hold together the corn and meat mixture.
