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. Cover and refrigerate for at least 2 hours, up to 8 hours.
02 - Whisk together ranch dressing, salsa, mayonnaise, lime juice, and chili powder in a small bowl until smooth. Refrigerate until serving.
03 - Preheat grill or grill pan to medium-high heat, approximately 400°F. Remove chicken from marinade and let excess drip off.
04 - Place chicken on preheated grill. Cook for 6-8 minutes per side until internal temperature reaches 165°F and chicken is cooked through with nice grill marks.
05 - Transfer grilled chicken to a baking sheet. Spread 2-3 tablespoons of Mexi-Ranch sauce over each breast. Top evenly with shredded Mexican cheese blend.
06 - Place baking sheet under oven broiler for 1-2 minutes until cheese is bubbly and melted, watching closely to prevent burning.
07 - Plate each chicken breast and top generously with tortilla strips and pico de gallo. Serve immediately while hot.
