01 - Bring a large pot of salted water to a boil. Add the orzo pasta and cook according to package instructions, approximately 8 to 10 minutes, until al dente. Add the asparagus during the final 2 minutes of cooking, then drain and rinse under cold water to halt the cooking process.
02 - In a small bowl, whisk together extra virgin olive oil, fresh lemon juice, lemon zest, white wine vinegar, Dijon mustard, minced garlic, salt, and black pepper until fully emulsified.
03 - In a large mixing bowl, combine cooked orzo, blanched asparagus, cherry tomatoes, red onion, and chopped parsley. Pour the lemon vinaigrette over the mixture and toss until evenly coated.
04 - Fold in the crumbled feta cheese gently until incorporated. If desired, adjust seasoning to taste.
05 - Serve the salad chilled or at room temperature. For optimal flavor, allow to rest for 10 minutes before serving.
