Cook the Orzo: Bring a large pot of salted water to a boil. Add the orzo and cook according to package instructions (usually 8–10 minutes), until al dente. Drain and rinse under cold water to stop cooking and cool the pasta quickly. Set aside.
Prepare the Lemon Vinaigrette: In a small bowl or jar, whisk together olive oil, lemon juice, lemon zest, Dijon mustard, honey, garlic, salt, and pepper until emulsified. Taste and adjust seasoning — add more lemon juice for tang or honey for balance.
Assemble the Salad: In a large mixing bowl, combine cooked orzo, cherry tomatoes, cucumber, red onion, olives, parsley, and dill (if using). Pour the vinaigrette over the salad and toss gently until everything is well coated.
Add Feta and Chill: Gently fold in crumbled feta cheese. Refrigerate for at least 15–20 minutes to allow the flavors to meld together before serving.
