In a medium bowl, combine ½ cup mayonnaise, ¼ cup sour cream, the juice of one freshly squeezed lime, and 1 tablespoon taco seasoning. Whisk until smooth and creamy. Cover and refrigerate for about 15 minutes.

In a large mixing bowl, add 4 cups of coleslaw mix, 1 diced red bell pepper, 1 diced orange bell pepper, 1 cup of well-rinsed black beans, and 1 cup of drained corn. Toss gently to combine.

Pour the chilled dressing over the vegetable mixture. Toss gently until all ingredients are evenly coated.

For a cooler coleslaw, cover it and let it sit in the refrigerator for another 30 minutes. Adjust seasoning if needed and serve immediately.
