01 - Whisk together lime juice, soy sauce, olive oil, Worcestershire sauce, cumin, chili powder, garlic powder, smoked paprika, salt, and pepper in a large bowl or zip-top bag. Add chicken breasts and coat thoroughly. Refrigerate for at least 2 hours, up to 8 hours for maximum flavor.
02 - Combine ranch dressing, salsa, mayonnaise, lime juice, and chili powder in a small bowl. Whisk until smooth and well blended. Refrigerate until serving time.
03 - Heat grill or grill pan to medium-high temperature, approximately 375-400°F.
04 - Remove chicken from marinade, allowing excess to drip off. Grill for 6-8 minutes per side until internal temperature reaches 165°F and chicken shows distinct grill marks.
05 - Transfer grilled chicken to a baking sheet. Spread 2-3 tablespoons of Mexi-Ranch sauce over each breast. Sprinkle Mexican cheese blend evenly over the top.
06 - Place under oven broiler for 1-2 minutes until cheese is fully melted and bubbly. Watch closely to prevent burning.
07 - Top each chicken breast with tortilla strips and a generous portion of pico de gallo. Serve immediately while hot.
