Begin by bringing a large pot of salted water to a rolling boil. Add your choice of dried uncooked pasta, and cook according to package instructions until al dente, typically 8-12 minutes. Once done, drain the pasta in a colander and rinse it under cold water for about 30 seconds to halt the cooking process. Set the pasta aside and let it cool completely.

In a large mixing bowl, combine the cooled pasta with a hearty portion of rinsed black beans, sweet corn, diced tomatoes, chopped cilantro, and finely diced red onion. Gently toss all the ingredients together until evenly mixed, ensuring that the vibrant colors and textures are beautifully distributed.

In a separate small bowl, whisk together mayonnaise, sour cream, and chipotle in adobo for a creamy base. Add chili powder, cumin, garlic powder, onion powder, and fresh lime juice, blending thoroughly until smooth.

Pour the chipotle lime dressing over the pasta mixture, tossing gently to coat all the ingredients evenly. Taste and season with salt and pepper.

Serve immediately for a fresh hit of flavor or cover and chill in the refrigerator for at least 30 minutes to meld the flavors. Optionally, top with creamy slices of avocado right before serving.
