This is the BEST cornbread salad I have made! You won’t be disappointed! I used dark red kidney beans in place of the pinto and added chopped jalapenos to the cornbread. 
Layered Cornbread Salad
I have found the longer cornbread salad sits the better it is. I would make this the day before serving it.
Layered Cornbread Salad
1 pkg. (6 1/2 oz) cornbread and muffin mix
1 c. mayo
8 oz. sour cream
1 pkg. (0.4oz) dry ranch salad dressing mix
3 large tomatoes chopped
1/2 c. chopped green bell pepper
1/2 c. chopped green onion
1 can pinto beans, rinsed and drained
1 can (15 1/4 oz) whole kernel corn, drained
2 c. shredded cheddar cheese
Prepare cornbread and let cool. For dressing stir together mayo, sour cream and dressing mix; set aside.
In a different bowl combine tomatoes, bell pepper and onion. Measure 1/2 the tomato mixture and set aside.
Crumble cornbread into 1-inch pieces and arrange half over bottom of extra large serving bowl. Layer with half the pinto beans, half the corn, 3/4 c. shredded cheese and half the remaining tomato mixture. Repeat layers ending with the dressing. Sprinkle the reserved 1/2 c. tomato mixture and remaining 1/2 c. cheese. Cover and chill 2 to 24 hours.
