Marinate the chicken with salt, pepper, and a drizzle of olive oil for at least 30 minutes.
Cook the rice according to manufacturer’s instructions, using chicken broth instead of water.
In a blender, combine parsley, cilantro, olive oil, lemon juice, and garlic. Blend until smooth.
In a large skillet, heat olive oil over medium heat. Add the marinated chicken and cook for about 6-7 minutes on each side, or until golden brown and cooked through.
Once cooked, remove the chicken from the skillet and let it rest for a few minutes before slicing.
Combine the cooked rice with a portion of the green sauce, reserving some for serving.
Serve the sliced chicken over the rice and drizzle with the remaining green sauce.
