Add 4 quarts water to boil over high heat. Salt the water and add orzo and cook 8-10 minutes or until al dente. Drain well, then pour orzo into a bowl and toss with a tablespoon or two of extra virgin olive oil to keep it from sticking; set aside.
In a large mixing bowl, combine cherry tomatoes, onion, bell peppers, any herbs (like basil or parsley), chopped chicken and feta cheese.
In a separate small bowl, whisk together dressing ingredients.
Add orzo pasta to the vegetables/chicken bowl and toss to combine. Pour dressing over salad and toss well to evenly coat with dressing.
Refrigerate and when ready to serve, stir well and the pasta will absorb a lot of the dressing, so you can add a drizzle of extra virgin olive oil if needed. Add extra feta cheese or chopped herbs on top to garnish!
