2 cans (15 ounces each) pinto beans, rinsed and drained
4 medium tomatoes, chopped
1 medium green pepper, chopped
1 medium onion, chopped
10 bacon strips, cooked and crumbled
Preheat oven to 400°. Prepare cornbread batter according to package directions. Pour into a greased 8-in. square baking pan. Bake until a toothpick inserted in center comes out clean, 15-20 minutes. Cool completely in pan on a wire rack.
Coarsely crumble cornbread into a large bowl. In a small bowl, mix mayonnaise and relish.
In a 3-qt. trifle bowl or glass bowl, layer a third of the cornbread and half of each of the following: beans, tomatoes, pepper, onion, bacon and mayonnaise mixture. Repeat layers. Top with remaining cornbread. Refrigerate, covered, 2-4 hours before serving.
