Give your go-to chicken recipes a rest and try this whole roasted version with crispy chickpeas and a lemony cucumber-yogurt sauce.
Preheat oven to 475 degrees. Cut chicken along backbone on one side with shears; open like a book. Turn over; press flat on a rimmed baking sheet. Rub with 1 tablespoon oil; season with salt and pepper. Roast 25 minutes. Meanwhile, combine onion and vinegar in a large bowl. In another bowl, combine yogurt, cucumber, and lemon juice. Season both with salt and pepper.
Remove sheet from oven; scatter chickpeas and lemon slices around chicken. Season with salt and pepper. Drizzle with remaining oil. Roast until a thermometer inserted into thickest part ofbreast registers 165 degrees, about 15 minutes. Transfer chicken to a cutting board. Return sheet to oven; roast until chickpeas are crisp, 10 minutes. Cut chicken into pieces. Toss chickpea mixture and herbs with onion mixture. Serve, with chicken and yogurt sauce.
