I created this Casserole one night when my family decided to have sloppy joe's for dinner. Since I am not a fan of Sloppy Joe's my parents suggested Ham, onions and cheese over cornbread. But, I thought I would taste better with the ham and onions in the corn bread. so my parent said I could try it. when I tried it i found it to be better than I thought it would be. next time I may even try replacing some of the milk used with cream style corn.
Slice or chop onions thinly, then place in the iron/oven safe 10" skillet with a tbls. of oil or margarine. Start to caramelizing onions with a dash of salt and pepper on medium heat, stirring often.
While onions are caramelizing, cube up your ham and cheese, and mix up the cornbread mix, following box directions. Set all aside. (let corn bread mix set for at least 3-4 minutes.)
Once onions are fully caramelized remove from skillet, add ham to skillet and saute' until it becomes golden brown on at least one side.
Once ham is browned, remove from heat and add onions back to pan. Pour cornbread mix over ham and onion and mix them all together in the pan.
Place in the preheated oven and bake for 15 minutes. Remove from oven, sprinkle cheese oven the top and return to oven. Bake an additional 5 minutes or until the cheese is melted. Remove from oven and serve immediately.
