Roast Chicken and Butternut Squash

Adjust oven rack to lower-middle position and preheat oven to 400 degrees.

Place the chicken, breast-side up in a roasting pan. Season generously with salt and pepper and drizzled with 3 tablespoons olive oil and all of the vinegar.

Transfer to the oven and roast the chicken for 45 minutes. Add squash and toss with pan drippings. Return to oven and continue to cook for another 30 minutes. Add croutons, toss again with pan drippings and return to oven to finish cooking, until the chicken breast registers 150°F on an instant-read thermometer, the squash is tender and lightly browned and the croutons are crispy, about 15 minutes more.

Remove from oven and let chicken rest until cool enough to handle. Shred meat from bones with fingers.

Transfer croutons, squash and 2 cups of torn chicken to a large bowl. Add arugula and grapes.

Whisk together cider vinegar, remaining 4 tablespoons olive oil, and mustard in a small bowl. Season with salt and pepper. Toss dressing with salad and serve immediately.
