01 - In a mixing bowl, combine lime juice, olive oil, minced garlic, honey, chili powder, ground cumin, paprika, salt, and black pepper. Whisk thoroughly to form an even marinade.
02 - Arrange chicken breasts in a resealable bag or shallow dish. Pour marinade over the chicken, ensuring all pieces are well coated. Refrigerate for a minimum of 15 minutes and up to 2 hours for enhanced flavor.
03 - Preheat a grill or grill pan to medium-high heat, preparing for direct grilling.
04 - Remove chicken breasts from marinade and allow excess to drip off. Grill each breast for 6 to 8 minutes per side, or until cooked through and internal temperature reaches 165°F (74°C).
05 - While chicken grills, combine diced avocado, halved cherry tomatoes, finely chopped red onion, and chopped cilantro in a small bowl. Season lightly with salt and toss gently to blend.
06 - If including cheese, sprinkle shredded Monterey Jack or Cheddar on the chicken during the final 2 minutes of grilling to gently melt over the surface.
07 - Arrange grilled chicken on serving plates. Spoon avocado mixture atop each portion and finish with a squeeze of fresh lime. Garnish with additional cilantro and lime wedges as preferred.
