Bring a large saucepan of salted water to a boil. Add orzo and cook until tender, (check box for actual cook time). Drain and rinse with cold water.
While orzo cooks, whisk ingredients for dressing together in a mixing bowl.
Add cooked and cooled orzo to a large mixing bowl. Add tomatoes, cucumbers, and olives.
Pour dressing over the top and mix with two large spoons. Season with garlic salt, sea salt, and pepper. Garnish with parsley. Serve immediately.
**If you are not serving immediately, reserve 1/4 cup of dressing to refresh the salad**
