In a blender, mix 2 tbsp. EVOO, 1/3 cup cilantro, the garlic, spices, lemon zest and lemon juice until ground into a paste. Season with 1/4 tsp. salt and pepper.
In a medium saucepan of boiling, salted water, cook the carrots until crisp-tender, about 3 minutes. Drain, rinse under cold water and return to the pan. Stir in the honey and remaining 1 tbsp. EVOO.
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. Broil until the tops are browned, about 8 minutes. Using tongs, flip the chicken; broil until cooked through, about 5 minutes more.
Meanwhile, prepare the couscous according to package directions; let cool. Stir in half of the remaining cilantro.
Rewarm the carrots; season. Divide the chicken, couscous and carrots among plates. Sprinkle with the remaining cilantro and serve with the lemons.
