Preheat oven to 400°F (200°C). Wrap washed beets in aluminum foil and roast on a baking sheet for 45-60 minutes until fork-tender.

Once roasted, peel the beets and slice into wedges. While they cool, peel and segment the oranges.

In a bowl, whisk together olive oil, honey, salt, and pepper for dressing.

In a serving bowl, combine sliced beets and orange segments. Top with crumbled feta and sprinkle pistachios.

Drizzle dressing over the salad before serving and toss gently to combine.
