In a small bowl, combine the mayonnaise, sour cream, fresh lime juice, and taco seasoning. Stir until well blended. This creamy and tangy dressing is the heart of the coleslaw, bringing together all the flavors and adding that signature Tex-Mex flair.
Step 2: Assemble the Coleslaw
In a large serving bowl, combine the tri-color coleslaw mix, diced red bell pepper, halved grape tomatoes, drained and rinsed black beans, grilled or blackened corn, minced jalapeno, and chopped cilantro. Gently toss the vegetables together to ensure an even distribution of ingredients.
Step 3: Combine the Dressing and Vegetables
Pour the prepared dressing over the vegetable mixture. Using a large spoon or spatula, gently fold the dressing into the coleslaw, making sure every piece is coated with the creamy mixture. Be careful not to overmix, as you want to maintain the crunch of the vegetables.
Step 4: Season and Chill
Season the coleslaw with kosher salt and freshly ground black pepper to taste. Cover the bowl with plastic wrap or transfer the coleslaw to an airtight container. Refrigerate for at least 30 minutes before serving. This allows the flavors to meld together, creating a more cohesive and delicious dish.
