Make your cornbread topping by combining the corn muffin mix, the cheese, milk and diced jalapenos and spread on top of the sloppy joe mixture in the casserole dish
Bake at 400 for 15 minutes. Do a knife test by running a butter knife through the center of the casserole and see if the cornbread is cooked through. If the knife does not come out clean, cover the dish with foil and bake for another 10 minutes.
