Prepare the Vinaigrette: In a small jar, combine all vinaigrette ingredients: extra virgin olive oil, lemon juice, red wine vinegar, minced garlic, Dijon mustard, dried oregano, and black pepper. Seal the jar tightly and shake vigorously for 30 seconds until the mixture is creamy and fully emulsified. Set it aside to allow the flavors to meld.
Cook the Orzo: Bring a large stockpot of unsalted water to a rolling boil. Add the whole wheat orzo and cook according to package directions, typically 9-11 minutes, until it is tender with a slight al dente chew.
Prepare the Vegetables: While the orzo is cooking, prepare all the fresh components. Halve the cherry tomatoes, slice the cucumbers and olives, dice the bell pepper, and thinly slice the red onion. Roughly chop the fresh mint and parsley. Place all the prepared vegetables and olives into your large mixing bowl.
Infuse the Pasta: As soon as the orzo is cooked, drain it well in a fine-mesh strainer. Do not rinse it. Immediately transfer the hot orzo to the large bowl with the vegetables. Pour about half of the prepared vinaigrette over the warm pasta and toss gently. This step allows the orzo to absorb the dressing for maximum flavor.
Combine the Salad: Add the rinsed chickpeas and sliced red onion to the bowl. Drizzle the remaining vinaigrette over everything and toss gently until every ingredient is lightly coated.
Finish and Serve: Gently fold in the crumbled feta cheese and the chopped fresh mint and parsley, reserving a small amount of herbs for garnish. For the best flavor, let the salad rest for at least 10 minutes at room temperature before serving. Garnish with the remaining fresh herbs and enjoy.
