Creating the Zesty Southwest Chicken Salad is straightforward if you follow these simple steps:

1. Prepare the Chicken: If not using pre-cooked chicken, cook the chicken breast in a pan over medium heat until fully cooked. Shred and set aside to cool.
2. Cook the Corn: If using fresh corn, cook in boiling water until tender, about 5-7 minutes. Drain and cool. If using canned corn, drain and rinse before use.
3. Combine Ingredients: In a large bowl, add shredded chicken, corn, black beans, cherry tomatoes, diced bell peppers, red onion, avocado, and cilantro.
4. Make the Dressing: In a small bowl, whisk together lime juice, olive oil, chili powder, cumin, salt, and pepper until well combined.
5. Toss Salad: Pour the dressing over the salad mixture. Toss gently to coat all ingredients evenly with the dressing.
6. Add Cheese: Sprinkle the shredded cheese over the top of the salad and give it one last gentle toss to mix.
7. Chill (Optional): If time allows, let the salad chill in the refrigerator for about 15-30 minutes to allow flavors to meld.
8. Serve: Serve immediately, or store in an airtight container in the fridge for later use.

This step-by-step guide is designed to help ensure that you create this incredible salad with ease.
