In a large mixing bowl, combine the coleslaw mix, sweet corn kernels, chopped green onions, and pickled jalapeños. Gently toss these vibrant ingredients together until evenly distributed.

In a separate small bowl, whisk together mayonnaise, apple cider vinegar, kosher salt, and freshly ground black pepper until smooth and well combined.

Pour the creamy dressing over the coleslaw mixture in the large bowl and gently fold the dressing into the coleslaw, ensuring every piece is well coated.

Taste your coleslaw mixture and adjust the seasoning according to your preferences. Add more salt, pepper, or jalapeños if desired.

Cover the coleslaw and chill in the refrigerator for at least 30 minutes to allow flavors to meld beautifully.

When ready to serve, give the coleslaw a final gentle toss and present it in a colorful serving bowl.
