Preheat the broiler. In a mini food processor, pulse the garlic with the cracked pepper and 2 teaspoons of kosher salt until the garlic is minced. Add 1 cup of the cilantro, the lime juice, crushed red pepper and 1 tablespoon of olive oil and pulse until a chunky paste forms. Rub the paste under the skin and all over the chicken breasts. Transfer the chicken to a baking sheet and let stand at room temperature for 10 minutes.
