Preheat your oven to 400°F (200°C).
In a large bowl, toss the beet wedges and carrot rounds with olive oil, salt, and black pepper until evenly coated.
Spread the beets and carrots on a baking sheet in a single layer. Roast in the preheated oven for 25-30 minutes, or until tender and slightly caramelized, stirring halfway through.
Remove the vegetables from the oven and let them cool slightly. Drizzle with balsamic vinegar and toss to combine.
On a serving platter, arrange the roasted beets and carrots. Tear the burrata cheese and place it in the center.
Top with fresh arugula or mixed greens and sprinkle with chopped walnuts if using. Garnish with fresh herbs.
Serve immediately or chill for 15-20 minutes before serving for a refreshing dish.
