01 - Preheat the oven to 400°F.
02 - Wrap each beet individually in foil and place on a baking sheet. Roast for 40-50 minutes, or until tender when pierced with a knife. Remove from oven and let cool slightly.
03 - Once cool enough to handle, peel the beets—the skins should slip off easily—and cut into wedges or slices.
04 - In a small bowl, whisk together olive oil, balsamic vinegar, Dijon mustard, honey, salt, and pepper until emulsified.
05 - In a large salad bowl, arrange the mixed greens. Top with beet slices, goat cheese crumbles, and toasted nuts. Add apple or pear slices if using.
06 - Drizzle with the vinaigrette just before serving and toss gently to combine.
