Cook the orzo in a saucepan according to package directions until al dente, then drain and rinse under cold water to stop cooking; set aside to cool.
In a large bowl, combine the cooled orzo, drained chickpeas, chopped cucumber, crumbled feta, chopped fresh dill, and diced red onion.
In a small bowl, whisk together the olive oil, fresh lemon juice, minced garlic, and finely chopped dill; season with salt and freshly ground black pepper to taste.
Pour the dressing over the salad and toss gently until everything is evenly coated.
Serve immediately or chill before serving if desired.
Notes
Rinse the orzo under cold water to stop cooking and remove excess starch.
Use canned chickpeas drained well to avoid watery salad.
Adjust lemon and salt to taste for brighter or milder flavor.
For best flavor, let the salad rest 15–30 minutes before serving.
