Preheat oven to 400°F (200°C).
Pat the chickpeas dry with paper towels.
Toss chickpeas with olive oil, oregano, garlic powder, paprika, salt, and pepper.
Spread chickpeas on a baking sheet in a single layer.
Roast for 25–30 minutes, stirring halfway through, until golden and crispy.
Allow chickpeas to cool slightly.
In a large bowl, combine cucumber, tomatoes, red onion, parsley, feta cheese, and olives.
In a small bowl, whisk together olive oil, lemon juice, red wine vinegar, garlic, oregano, salt, and pepper.
Add roasted chickpeas to the salad.
Pour dressing over the salad and toss gently to combine.
Serve immediately for maximum crunch.
