In a food processor, combine the baby spinach, chives, garlic, pine nuts, Parmesan cheese, extra-virgin olive oil, lemon juice and salt. Puree until the mixture is finely chopped.
Cover and refrigerate until you are ready to use the pesto. When ready to use, bring to room temperature.
The chicken:
Preheat the grill to high heat and then turn down to medium heat.
Rub each of the chicken breasts with 1 teaspoon olive oil. Season with salt and pepper.
Place the chicken breasts on the grill and cook until done, about 5 minutes per side. Remove the chicken from the grill, let rest for 5 minutes, and then slice on a diagonal.
Serve the chicken breasts with the pesto over top.
