Cook the orzo according to package directions. Drain; rinse with cold water and set aside.
In a small bowl, whisk the seasoning mix together with the olive oil, vinegar, and sugar until emulsified. In a large bowl, combine the orzo, olives, red pepper, and feta cheese with just enough dressing to lightly coat the salad. Chill covered for at least 2 hours. Serve garnished with the chopped basil.
