Ingredients

24 ounces Brussels sprouts (about 8 cups), halved or quartered, if large

24 ounces grapes

2 tablespoons extra-virgin olive oil

4 tablespoons fresh thyme

Coarse salt and freshly ground pepper

2 teaspoons balsamic vinegar

1/2 cup walnuts, toasted and coarsely chopped

Preparation

Heat oven to 450 degrees. On 2 rimmed baking sheets, toss Brussels sprouts and grapes with oil and thyme. Season with salt and pepper. Roast, until caramelized and tender, about 20 minutes.

Drizzle each tray with 1 teaspoon vinegar and scrape up any caramelized bits with a wooden spoon. Toss in walnuts.
