Rinse and drain the chickpeas, then pat them dry with a paper towel.
Halve the cherry tomatoes, dice the cucumber, thinly slice the red onion, and chop the parsley.
Pit and halve the kalamata olives if needed.
In a small bowl or jar, whisk together the olive oil, lemon juice, red wine vinegar, oregano, minced garlic, salt, and black pepper until well combined.
Let the dressing sit for about 5 minutes to allow the flavors to meld.
In a large mixing bowl, combine the chickpeas, cherry tomatoes, cucumber, red onion, and olives.
Drizzle the dressing over the top and gently toss everything together until evenly coated.
Sprinkle the crumbled feta cheese and chopped parsley over the salad.
Give it a final light toss, being careful not to break up the feta too much.
If time allows, let the salad sit for 15–20 minutes before serving. This helps the flavors blend beautifully.
Serve chilled or at room temperature.
Enjoy as a light meal, side dish, or pair it with grilled chicken, fish, or warm pita bread.
