Prepare the chili lime chicken according to its recipe, grill or cook until done, then slice or chop; set aside.
Make the chipotle ranch dressing according to its recipe and refrigerate until ready to use.
While the chicken marinates or cooks, wash and prep the salad ingredients: chop the romaine, halve the cherry tomatoes, drain and rinse the black beans, remove corn kernels, mince the red onion, grate or measure the cheese, and slice or chop the avocados (keep avocados separate if storing).
For immediate serving, combine the romaine, cherry tomatoes, black beans, corn, red onion, cheese, pepitas/sunflower seeds and sliced chicken in a large salad bowl; toss gently with chipotle ranch or serve the dressing on the side.
If making for leftovers, toss all ingredients except avocados and tortilla chips in a large bowl; store avocados, chips and dressing separately and add just before serving to prevent sogginess.
Optional: set up a salad bar so guests can add tortilla chips and avocados to taste.
