Cook the Beets: Wash beets thoroughly. Roast at 400°F (200°C) for 35–45 minutes or boil until tender. Let them cool, peel, and dice.
Prepare the Salad Base: In a large mixing bowl, combine diced beets, crumbled feta, sliced red onions, and olives. Add fresh parsley. Toss gently to mix evenly.
Make the Dressing: In a small bowl, whisk together olive oil, lemon juice, honey (if using), salt, and pepper until well combined.
Combine: Drizzle the dressing over the salad and toss gently to coat all ingredients. Taste and adjust seasoning if necessary.
Serve: Transfer to a serving bowl and garnish with nuts or additional herbs if desired. Serve immediately or chill for later.
