In a large mixing bowl, combine the cole slaw mix, corn, minced jalapeño, chopped cilantro, and sliced green onions. Mix until colors are evenly distributed.

In a small bowl, whisk together the mayonnaise, lime juice, sugar, garlic powder, salt, and pepper until smooth.

Drizzle the dressing over the slaw mixture and fold together until all veggies are coated.

Cover with plastic wrap or transfer to an airtight container, and refrigerate for at least 30 minutes.
