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 coat thoroughly.
02 - Cover and refrigerate chicken for at least 2 hours, preferably up to 8 hours, allowing flavors to penetrate the meat.
03 - Whisk together ranch dressing, salsa, mayonnaise, lime juice, and chili powder in a small bowl until smooth. Refrigerate until serving.
04 - Heat grill or grill pan to medium-high temperature, approximately 375-400°F.
05 - Remove chicken from marinade, allowing excess to drip off. Grill for 6-8 minutes per side until internal temperature reaches 165°F and chicken is cooked through.
06 - Transfer grilled chicken to a baking sheet. Spread 2-3 tablespoons of Mexi-Ranch sauce over each breast and top evenly with shredded Mexican cheese.
07 - Place under oven broiler for 1-2 minutes until cheese is bubbly and melted. Watch closely to prevent burning.
08 - Plate each chicken breast topped with crunchy tortilla strips and a generous spoonful of fresh pico de gallo.
