In a large mixing bowl, combine shredded chicken, chopped romaine lettuce, halved cherry tomatoes, rinsed black beans, and corn. Gently toss together.

In a blender, add avocado, Greek yogurt, lime juice, cumin, and salt and pepper. Blend until smooth and creamy.

Pour the dressing over the salad mixture and toss until evenly coated.

Sprinkle with shredded cheese, garnishing with cilantro and jalapeños if desired.

Serve immediately in bowls.
