FOR THE CORN: Preheat your grill to low. Peel off the husk, strip away all the silk and place the corn on grill grates. Turn once and grill until bright yellow and kernels are tender. Increase the heat to medium-high and continue to grill until a few kernels char. Charring the corn is totally optional.
Combine all ingredients into a large bowl, cover and refrigerate until ready to serve.
Toss once more before serving. Serve with tortilla chips or on tacos, enjoy!
