Combine ¾ cup cottage cheese, ⅓ cup herbs, ¼ cup feta, 1 tablespoon oil, 1 teaspoon lemon zest, 3 tablespoons lemon juice, the grated garlic, ½ teaspoon pepper and ½ teaspoon salt in a blender; process until smooth, about 1 minute, stopping to scrape down the sides as needed.
Transfer the dressing to a large bowl. Add sliced cucumbers, rinsed chickpeas and halved tomatoes; toss to coat. Garnish with additional herbs, if desired.
