01 - Set your grill to medium-high heat, targeting approximately 400°F. Allow grates to fully heat for proper searing.
02 - In a small mixing bowl, combine the olive oil, ground cumin, garlic powder, smoked paprika, salt, and black pepper until a uniform paste forms.
03 - Rub the marinade mixture evenly over both sides of each chicken breast, ensuring full coverage for consistent flavor.
04 - Place the seasoned chicken onto the hot grill. Cook for 5 to 6 minutes per side until the internal temperature reaches 165°F and juices run clear.
05 - During the final 2 minutes of grilling, spoon 2 to 3 tablespoons of salsa verde over each chicken breast and lay a slice of Pepper Jack cheese on top. Close the grill lid and allow the cheese to melt completely.
06 - Transfer the chicken off the grill and let it rest for 5 minutes to allow juices to redistribute throughout the meat.
07 - Scatter chopped cilantro and diced red onion over each piece. Serve with fresh lime wedges on the side.
