Whisk together all dressing ingredients, then set aside.
Pre-heat your grill to medium.
Meanwhile, prepare your corn. Peel off the outer 3-4 husk layers from each cob. Carefully peel back the rest of the husk, leaving it attached at the base. Remove corn silks, then fold the husks back over the corn.
Grill the corn for 15 minutes, rotating it every 5 minutes. The husk will get charred, as will bits of the corn inside. Allow the corn to cool while you cut the remaining salad ingredients.
Once the corn has cooled, peel off the husks. Then, hold each ear of corn with the flat base down on a plate or cutting board. Use a large knife to cut the kernels from the cob by slicing close to the base of the kernels.
Mix all salad ingredients together, then add and mix in the dressing, reserving ¼ cup for later.
Cover the salad, then move to the fridge for at least 1-2 hours or overnight.
When ready to serve the salad, mix in the reserved dressing and adjust the salt and pepper to taste.
