01 - Preheat the 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 slice into wedges.
02 - While the beets roast, toast the walnuts in a dry skillet over medium heat for 3 to 4 minutes, stirring frequently until fragrant. Remove from heat and set aside.
03 - In a small bowl, whisk together olive oil, balsamic vinegar, Dijon mustard, honey, salt, and freshly ground black pepper until emulsified.
04 - Arrange mixed salad greens on a serving plate or divide among individual plates. Top with roasted beet wedges, crumbled goat cheese, and toasted walnuts.
05 - Drizzle the prepared dressing over the salad immediately before serving.
