This corn salsa is easy to make and perfect for sharing with others. This will be a hit at your next tailgate or house party. It is one of my favorite dishes to eat and make. I use grilled corn in this recipe, but you can use frozen corn or a can of corn. You can also add avocado to the corn salsa if you want. Adjustments can be made to your tastes such as less onion or no onion at all.
