Halve the cherry tomatoes, dice the cucumber into 1/2-inch pieces, slice the red onion thinly, and halve the black olives. Place all in a large mixing bowl.
Add the drained and rinsed chickpeas, crumbled feta cheese, and chopped fresh dill to the bowl with the vegetables.
In a small bowl or jar, whisk together the olive oil, lemon juice, minced garlic, dried oregano, salt, and pepper until well combined.
Pour the dressing over the salad and toss gently to coat all ingredients evenly. Transfer to a glass serving bowl and serve immediately.
