For the salad:
To roast the butternut squash:
Scoop the seeds out of each half of the squash and place cut side up on a baking sheet lined with parchment paper. Brush each half with olive oil (about 2 tablespoons total) then sprinkle with about ½ teaspoon kosher salt and ¼ teaspoon black pepper.
Roast in a 400-degree oven for about 1 hour or until the squash is tender when pierced with a sharp knife. When the squash is cool enough to handle, peel and cut into cubes.
To roast the beets:
Trim the tops and roots off the beets, peel and cut into pieces, about 2″ each. (Quick tip: wear food service gloves to prevent your hands from getting stained from the beet juice.) Toss the beets with 2 tablespoons of the olive oil and spread out in a single layer on a baking sheet lined with foil. Sprinkle with ½ teaspoon kosher salt and ¼ teaspoon black pepper.
Roast at 400-degrees for 35 to 40 minutes, stirring about every 15 minutes. Cook until the beets are cooked through and very tender when pierced with a sharp knife.
To roast the carrots:
Scrub or peel the carrots and cut into pieces, about 3” to 4”. Place the carrots on a rimmed baking sheet lined with parchment paper. Drizzle 2 tablespoons of the olive oil over the carrots then toss to coat all sides. Spread the carrots out into a single layer. Sprinkle with ½ teaspoon kosher salt and ¼ teaspoon black pepper.
Roast the carrots in a 400-degree oven for 40 minutes or until they are tender when pierced with the tip of a sharp knife. Cooking time will vary depending on the size of your carrots - start checking them after 30 minutes.
To make the vinaigrette:
Place the Dijon mustard a small mixing bowl. Pour in the red wine vinaigrette and chestnut honey. Add the kosher salt and black pepper, stir to blend.
Pour the sunflower oil and the olive oil in and blend together using an immersion blender. Makes about 2 cups so you will have enough for more than one salad.
To assemble the salad:
Spread the field greens across the bottom of the platter. Arrange the roasted vegetables along with the sliced pears and oranges around and on the greens. Sprinkle the cranberries and pecans over the top.
Drizzle a portion of the vinaigrette over the salad.
