Prepare the vegetables: Dice the cucumber and red bell pepper, halve the cherry tomatoes, and thinly slice the red onion. Chop the fresh parsley.
Combine the ingredients: In a large salad bowl, combine the chickpeas, diced cucumber, cherry tomatoes, red onion, Kalamata olives, crumbled feta cheese, and chopped red bell pepper.
Make the dressing: In a small bowl, whisk together the olive oil, lemon juice, dried oregano, salt, and pepper until well combined.
Dress the salad: Pour the dressing over the salad and gently toss to coat all the ingredients evenly.
Garnish and serve: Sprinkle the fresh parsley over the top as a garnish. Serve the salad immediately or refrigerate for 30 minutes to allow the flavors to meld.
