In a blender, combine the tomatillos, onion, garlic, jalapeno pepper, cilantro, lime juice, olive oil, cumin, paprika, salt, and pepper. Blend until smooth.
Place the chicken breasts in a shallow dish and pour the tomatillo sauce over them. Make sure the chicken is fully coated. Cover and let it marinate in the refrigerator for at least 1 hour, or overnight for best results.
Preheat the grill to medium-high heat. Remove the chicken from the marinade, allowing any excess sauce to drip off. Discard the remaining marinade.
Grill the chicken breasts for about 6-8 minutes per side, or until they reach an internal temperature of 165°F (74°C). The cooking time may vary depending on the thickness of the chicken breasts.
Remove the chicken from the grill and let it rest for a few minutes before slicing.
Serve the tomatillo chicken breasts with your choice of side dishes and garnish with additional fresh cilantro, if desired.
