Spray grill and corn with nonstick cooking spray. Sprinkle the corn with a little salt and pepper. Grill until corn is tender about 8-10 minutes. Turn corn every 1-2 minutes to make sure it does not burn.
To make the rice bring water to a boil. Add in rice and simmer for 5 minutes, covered. Take off of the heat and let it sit for an additional 5 minutes to soak up the water, covered. Fluff rice with fork. Set aside and allow to cool.
Meanwhile add the rest of the ingredients to a large bowl. Toss to combine. Add in the cooled rice and toss. I like to refrigerate it before serving but you can always serve as is.
