01 - Preheat your grill to medium-high heat (about 400°F).
02 - Pat the chicken breasts dry. In a small bowl, combine olive oil, garlic powder, cumin, smoked paprika, salt, and pepper. Rub this mixture evenly over each chicken breast.
03 - Grill the chicken for 6–7 minutes per side, or until cooked through and internal temperature reaches 165°F.
04 - In the last 2 minutes of grilling, top each breast with ¼ cup salsa verde and a slice of pepper jack cheese. Close the grill lid to melt the cheese.
05 - Remove chicken from the grill and let it rest for 5 minutes.
06 - Garnish with fresh cilantro and serve with lime wedges, avocado slices, and diced tomatoes if desired.
