My ex got this recipe off of the Food Network sometime back in '96.

9x13" casserole or lasagna pan

Bottom layer: Jiffy cornbread mix, unbaked. I used two boxes, added the eggs and milk, stirred and spread in the pan.

Next layer: browned ground beef cooked with garlic, diced sweet onion and diced sweet pepper.

Next layer: Diced tomatoes cooked with diced red onion.

Next layer: Black beans sauteed with chopped scallions.

Next layer: Corn niblets mixed with sour cream.

Top layer: Monterey Jack cheese. I had cheddar on hand today so I used cheddar.

Adapt how you wish. Bake until bubbly and browned-per-your-preference on top.
