Cook the orzo pasta according to package instructions. Drain and rinse under cold water to cool.

In a large bowl, combine the cooled orzo, cherry tomatoes, cucumber, red onion, feta cheese, and parsley.

In a small bowl, whisk together the olive oil, lemon juice, garlic powder, salt, and pepper.

Pour the dressing over the pasta salad and toss gently to combine all ingredients.

Chill in the refrigerator for at least 30 minutes before serving to allow flavors to meld.
