01 - Preheat oven to 400°F. Wrap each beet individually in aluminum foil and place on a baking sheet. Roast for 40 to 50 minutes, or until tender when pierced with a fork. Allow to cool, then peel and cut into wedges.
02 - While beets roast, toast walnuts in a dry skillet over medium heat for 3 to 4 minutes, stirring frequently until fragrant. Remove from heat and set aside.
03 - Whisk together olive oil, balsamic vinegar, Dijon mustard, honey, salt, and pepper in a small bowl until emulsified.
04 - Arrange salad greens on a serving platter or divide among plates. Top with roasted beet wedges, crumbled goat cheese, and toasted walnuts.
05 - Drizzle the prepared dressing over the salad just before serving.
