Ingredients
1 1/2 pounds boneless, skinless chicken thighs (about 5), cut into 1 1/2-inch-wide strips
3 tablespoons extra-virgin olive oil, divided, plus more for dressing
Coarse salt and freshly ground pepper
2 medium zucchini, cut crosswise into 1-inch-thick rounds
16 medium cipollini onions (about 10 ounces), peeled
16 medium cremini mushrooms (about 8 ounces), trimmed
1 lemon, zested and juiced
1/2 cup coarsely chopped fresh flat-leaf parsley leaves
Preparation
Soak ten 12-inch wooden skewers in water 30 minutes; drain. Preheat grill over medium-high heat. Meanwhile, toss chicken with 1 tablespoon oil; season with salt and pepper. Toss vegetables with remaining 2 tablespoons oil; season with salt and pepper. Divide chicken among 4 skewers. Skewer vegetables separately, using 2 skewers for each vegetable.
Place onion skewers on grill; cook 5 minutes. Add chicken and zucchini skewers; cook, turning occasionally, 5 minutes. Add mushroom skewers; cook until chicken and vegetables are cooked through and charred in places, about 10 minutes. Dress with lemon zest and juice, oil, and parsley. Skewers can be assembled and refrigerated up to 3 hours ahead; let sit at room temperature 30 minutes before grilling.
