Like other pasta salads, orzo can be served cold, but I prefer it at room temperature or only slightly chilled. To do this, transfer the dressing to the fridge for 10-15 minutes while the orzo cooks and you chop your veggies. Transfer the orzo to the refrigerator so it has time to cool to room temperature while you finish chopping your veggies (doesn't need long). Now everything will just slightly chilled - the perfect temperature to enjoy!
