1. Bring a large pot of salted water to a boil and cook the pasta according to the package instructions until al dente. Drain the pasta and let it cool slightly before adding it to the salad.

2. In a medium bowl, combine the room-temperature cream cheese, sour cream, olive oil, grated garlic, and chopped chives. Whisk the ingredients together until the dressing is smooth and creamy. Season with salt and pepper to taste.

3. In a small saucepan, melt the butter over medium heat. Add the smoked paprika, chili powder, and cayenne pepper, stirring to combine. Drizzle the spiced butter over the grilled or roasted corn kernels.

4. In a large salad bowl, toss together the cooked pasta, shredded romaine lettuce, the spiced corn, fresh basil, chopped cilantro, diced spicy cheddar cheese, and diced avocado. Pour the creamy dressing over the salad and gently toss to coat all the ingredients evenly.

5. You can serve the Healthy Street Corn Pasta Salad immediately or chill it in the refrigerator for 30 minutes to an hour to allow the flavors to meld. Garnish with additional crumbled cotija or feta cheese, fresh herbs, and a sprinkle of cayenne pepper for an extra kick.
