In a bowl, whisk together the salsa verde, lime juice, olive oil, garlic powder, salt, and pepper until well combined.
Place the chicken breasts in a resealable bag and pour the marinade over them. Seal the bag and massage to coat the chicken. Refrigerate for at least 1 hour or overnight for deeper flavor.
Preheat your grill to medium-high heat (400°F / 200°C).
Remove the chicken from the marinade, letting excess drip off. Grill for 6-7 minutes per side or until the internal temperature reaches 165°F (75°C).
Let the chicken rest for 5 minutes before slicing. Serve with extra salsa verde on top or on the side.
Notes
For healthier options, consider skinless chicken thighs or homemade, low-sodium salsa verde.
