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 until well combined.
02 - Add chicken breasts to the marinade, turning to coat completely. Seal and refrigerate for at least 2 hours or up to 8 hours for maximum flavor penetration.
03 - Combine ranch dressing, salsa, mayonnaise, lime juice, and chili powder in a small bowl. Whisk until smooth and refrigerate until serving.
04 - Heat grill or grill pan to medium-high temperature, approximately 375°F to 400°F.
05 - Remove chicken from marinade, allowing excess to drip off. Grill for 6 to 8 minutes per side until internal temperature reaches 165°F and chicken shows distinct grill marks.
06 - Transfer grilled chicken to a baking sheet. Spread each breast with 2 to 3 tablespoons of Mexi-Ranch sauce, then top evenly with shredded Mexican cheese.
07 - Place under oven broiler for 1 to 2 minutes until cheese is bubbly and lightly browned. Watch closely to prevent burning.
08 - Plate each chicken breast topped with tortilla strips and a generous spoonful of pico de gallo. Serve immediately while hot.
