In a large mixing bowl, combine the drained and rinsed chickpeas, cherry tomatoes, Kalamata olives, feta cheese, parsley, and cucumber.
In a small bowl, whisk together olive oil, red wine vinegar, lemon juice, dried oregano, salt, and pepper until well blended.
Pour the dressing over the salad ingredients and gently toss to combine, ensuring everything is evenly coated.
Taste and adjust seasoning if necessary, adding more salt, pepper, or lemon juice as desired.
Allow the salad to sit for at least 15 minutes before serving to let the flavors meld together.
Serve chilled or at room temperature, garnished with additional parsley if desired.
