Combine 1 (16-ounce) bag coleslaw mix, 1 (15-ounce) can drained and rinsed black beans, 1 ½ cups thawed and drained frozen corn, 1 ½ cup finely diced red bell pepper, ¼ cup finely diced seeded jalapeno pepper, ¼ cup sliced green onions, and ¼ cup chopped cilantro in a large bowl.
In another bowl, whisk together ½ cup mayonnaise, ½ cup sour cream, ¼ cup fresh lime juice, 2 tablespoons adobo sauce, 2 tablespoons taco seasoning, and ½ teaspoon garlic powder.
Pour the dressing over the slaw and toss to combine.
Just before serving, add 1 (9.75-ounce) bag chili cheese Frito chips to the slaw and toss to combine once more. Serve immediately.
Notes
Fridge: The chips will become soggy, and the salad will become more watery as it sits, so it is best consumed fresh. Leftovers may be stored in an airtight container in the refrigerator for up to 2 days.
Freezer: Not recommended
Make Ahead: Combine the dressing with everything in the salad except the Frito chips up to 24 hours before serving. Just before serving, stir in the chips.
