Bring a large pot of water to a boil. Add salt and the box of Orzo pasta. Cook until al dente (about 7 min). Srain the pasta and rinse with cold water to stop the cooking.
Allow the pasta to cool in a large bowl. Add these ingredients to the Orzo in the following order.
Hot Grilled Corn (The hot corn on the arugula is to wilt the arugula just a bit)
Lemon Juice and Zest
Salt & Pepper
Toss the cold pasta with all of these ingredients to coat evenly.
Corn Grilling Tip
Peel the corn husks back without removing them and LEAVE the silk on. This will give the corn a nice Smokey flavor. Rinse the corn thoroughly. Replace the husks and secure them with a piece of the husk.
Soak the cobs in water for 1 hour. Pull the husks back again and dry the corn. Brush butter on the cob and add salt and pepper. Replace the husks and place them on the grill for about 30 minutes rotating them periodically as the husk turns from green to brown. The moist husks will steam the corn and keep the corn from burning. Cut off the cob immediately and add on top of the arugula.
