Prepare the BeetsPreheat the oven to 400°F (200°C). Peel the beets and cut them into 1-inch cubes. Place the cubed beets on a baking sheet lined with parchment paper. Drizzle with a small amount of olive oil, sprinkle with salt and pepper, and toss to coat.
Roast the BeetsRoast the cubed beets in the preheated oven for 30-40 minutes, turning halfway through, until they are tender and lightly caramelized. Remove from the oven and allow them to cool slightly.
Assemble the SaladIn a large mixing bowl, combine the kale, roasted beets, dried cranberries, chopped walnuts, and crumbled goat cheese. Drizzle with the balsamic vinaigrette (recipe below) and toss to combine.
ServeTransfer the salad to a serving bowl and, if desired, garnish with additional goat cheese or chopped walnuts. Serve immediately.
Homemade Balsamic Vinaigrette
In a small bowl or jar, whisk together the balsamic vinegar, Dijon mustard, and honey (if using) until well combined.
Slowly drizzle in the olive oil while whisking constantly, or shake all the ingredients together in a sealed jar until emulsified.
Stir in the minced garlic (if using) and season with salt and pepper to taste.
