Make the Dressing: In a small bowl, whisk together the light mayonnaise, salsa, cayenne pepper, minced garlic, and fresh lime juice until smooth. Set the dressing aside while you prepare the rest of the salad.
⅓ cup light mayonnaise, ¼ cup salsa, ½ teaspoon cayenne pepper, 1 teaspoon minced garlic, 2 tablespoons fresh lime juice
Grill the Corn: Brush the corn with olive oil and season it with salt. Grill over medium-high heat for 5 to 10 minutes, turning often with tongs, until the kernels are tender and lightly charred.
2 ears corn, 2 teaspoons olive oil, Salt
Cut the Corn: Let the grilled corn cool slightly so you do not burn your fingers over a pasta salad, which feels unnecessary. Use a sharp knife to cut the kernels off the cobs.
Build the Salad: In a large mixing bowl, combine the baby spinach, shredded chicken, cooked bowtie pasta, grilled corn, avocado, black beans, cilantro, red onion, and cotija cheese.
3 cups fresh baby spinach, 2 cups shredded cooked chicken, 3 cups cooked bowtie pasta, 2 avocados, ½ cup canned black beans, 1 bunch fresh cilantro, ½ red onion, ½ cup crumbled cotija cheese or queso fresco
Dress and Toss: Pour the creamy salsa-lime dressing over the salad. Toss gently until everything is evenly coated, being careful not to mash the avocado unless you accidentally want pasta salad with a guacamole subplot.
Serve: Serve immediately for the freshest texture. To make it ahead, chill the salad ingredients and dressing separately, then toss everything together right before serving.
