01 - Combine lime juice, soy sauce, olive oil, Worcestershire sauce, cumin, chili powder, garlic powder, smoked paprika, salt, and black pepper in a large bowl or zip-top bag. Add chicken breasts and turn to coat thoroughly. Seal and refrigerate for at least 2 hours, up to 8 hours for maximum flavor penetration.
02 - Whisk together ranch dressing, salsa, mayonnaise, lime juice, and chili powder in a small bowl until smooth and fully combined. Cover and refrigerate until serving.
03 - Heat outdoor grill or indoor grill pan to medium-high temperature, approximately 400°F. Ensure grates are clean and lightly oiled to prevent sticking.
04 - Remove chicken from marinade, allowing excess liquid to drip off. Place chicken on preheated grill and cook for 6 to 8 minutes per side, until internal temperature reaches 165°F and meat is nicely charred with grill marks.
05 - Transfer grilled chicken to a baking sheet. Spread 2 to 3 tablespoons of Mexi-Ranch sauce evenly over each chicken breast. Top with shredded Mexican cheese, covering the sauce completely.
06 - Place baking sheet under oven broiler for 1 to 2 minutes, watching closely to prevent burning. Remove once cheese is fully melted and beginning to bubble.
07 - Plate each chicken breast topped with a generous handful of tortilla strips and a spoonful of fresh pico de gallo. Serve immediately while hot and crispy.
