Cook 1½ cups orzo according to package directions until al dente. Drain, rinse under cold water, and let cool. In a large bowl, combine the cooked orzo with 1 cup halved cherry tomatoes, 1 diced cucumber, ½ cup sliced Kalamata olives, ¼ cup finely chopped red onion, ½ cup crumbled feta cheese, and 2 tablespoons chopped fresh parsley. Whisk together 3 tablespoons extra virgin olive oil, 1 tablespoon lemon juice, 1 teaspoon red wine vinegar, 1 minced garlic clove, dried oregano, salt, and black pepper. Toss the salad with the dressing and chill for 20 minutes before serving for the best flavor.
