01 - In a large bowl or zip-top bag, combine lime juice, soy sauce, olive oil, Worcestershire sauce, cumin, chili powder, garlic powder, smoked paprika, salt, and black pepper. Add chicken breasts and coat thoroughly. Cover and marinate in refrigerator for at least 2 hours, preferably up to 8 hours.
02 - In a small bowl, whisk together ranch dressing, salsa, mayonnaise, lime juice, and chili powder until smooth. Refrigerate until ready to use.
03 - Preheat grill or grill pan to medium-high heat (approximately 375°F to 400°F). Remove chicken from marinade, allowing excess to drip off.
04 - Grill chicken breasts for 6 to 8 minutes per side, or until internal temperature reaches 165°F. Avoid flipping too frequently to develop proper grill marks.
05 - Transfer grilled chicken to a baking sheet. Spread each breast with 2 to 3 tablespoons of Mexi-Ranch sauce. Top evenly with shredded Mexican-blend cheese.
06 - Place under oven broiler for 1 to 2 minutes, watching closely to prevent burning, until cheese is bubbly and fully melted.
07 - Top each chicken breast with tortilla strips and a generous spoonful of pico de gallo. Serve immediately while hot.
