Preheat oven according to cornbread package. Grease casserole dish (I used 9 x 11 but a 9 x 13 inch should work too).
Brown meat with taco seasoning (I didn't use the whole pouch because the rotel adds some spiciness as well. I used about half a pouch) and drain off excess fat. Add onion and pepper and cook until tender. Add rotel, kidney beans, and corn and let simmer.
Meanwhile combine cornbread according to package directions. Add diced jalapeno and creamed corn.
Spoon thin layer of cornbread on the bottom of the pan. Top with meat mixture then add half of the cheese. Spoon the rest of the cornbread mixture on top and bake according to cornbread package. In the last 5 minutes of cooking top with the rest of the cheese and continue baking until cheese is melted.
