Bake 25 to 35 minutes or until toothpick inserted in center of topping comes out clean. Sprinkle remaining 1/4 cup cheese over hot casserole.
Make sure the Sloppy Joe mixture is piping hot when you spoon the batter on top, so that the corn bread bakes all the way through.
Deli potato salad or chips with carrot and celery sticks are perfect partners with this Sloppy Joe taste-alike casserole.
