Grill the chicken breasts and allow them to cool.
Once cooled, slice them into strips.
In a large mixing bowl, combine the chopped romaine lettuce, avocado, corn, black beans, jicama, and tomatoes.
Add the sliced chicken and Monterey Jack cheese to the salad.
Mix gently.
In a separate bowl, whisk together the ranch dressing and BBQ sauce.
Then pour over the salad mixture.
Toss the salad to ensure everything is well coated with the dressing.
Finally, top with tortilla strips.
