In a large pot heat waterfor the orzo until a rumbling boil.
Slice and dice the cucmber, onion, tomato and kalamata olives.
Once pasta water is boiling, add a handful of salt to the water. Place the orzo in the water and cook for 8-10 minutes. (If you prefer to have a more aldente or more cooked.)
Drain Pasta and place in a large bowl. Drizzle olive oil and mix through. Let pasta cool. It is NOT recommended to rinse the pasta under cool water. This will release the startch that is needed to help adhere the pasta to the dressing.
