In a blender, mix 1 tbsp. olive oil, 1 cup cilantro, garlic, spices, lemon zest and lemon juice until ground into a paste. Season with 1/4 tsp. each salt and pepper.
Position a rack 4 to 5 inches from the top of the oven and preheat the broiler.
In a medium bowl, toss the chicken with the spice paste to coat. Arrange on a foil-lined baking sheet; season with salt and pepper.
Broil until the tops are browned, about 8 minutes. Using tongs, flip the chicken; broil until cooked through, about 5 minutes more. Remove and serve.
