Place half of crumbled cornbread in the bottom of a 4-quart bowl and top with half the beans.
In a medium bowl, combine tomatoes, green peppers and onions. Layer half of this mixture over the beans. Then layer half the cheese, bacon, corn and then salad dressing. Repeat layers in the same order.
Cover and chill 2-3 hours (best if overnight) before serving. Garnish with green or yellow onion rings and tomato slices.
