Rinse and drain the chickpeas thoroughly and place in a large mixing bowl.
Add cubed beets, diced red onion, and chopped parsley to the chickpeas.
In a separate small container, whisk together olive oil, lemon juice, minced garlic, oregano, salt, and pepper until fully emulsified.
Pour the lemon garlic vinaigrette over the salad ingredients and toss gently to combine.
Carefully fold in the crumbled feta cheese to avoid excessive staining from the beets.
Serve immediately or refrigerate for 30 minutes to allow flavors to develop.
