01 - Whisk together lime juice, olive oil, minced garlic, honey, chili powder, ground cumin, paprika, salt, and black pepper in a mixing bowl.
02 - Place chicken breasts in a resealable bag or shallow dish. Pour marinade over chicken, ensuring thorough coating. Refrigerate for 15 minutes or up to 2 hours for enhanced flavor.
03 - Heat grill or grill pan to medium-high.
04 - Remove chicken from marinade, allowing excess to drip off. Grill chicken for 6 to 8 minutes per side, or until internal temperature reaches 165°F (74°C) and juices run clear.
05 - While chicken grills, combine diced avocado, cherry tomatoes, red onion, and chopped cilantro in a bowl. Lightly season with salt and toss gently.
06 - If using cheese, sprinkle over chicken during final 2 minutes of grilling to allow melting.
07 - Top grilled chicken with avocado mixture and a squeeze of fresh lime. Garnish with additional cilantro and lime wedges as desired.
