You can make this year 'round but it's our new favorite thing for when it's too hot to turn the over on.
Remove corn from the cob & roast on the stove top. You can also do this on the grill...obviously you grill the corn before you remove it from the cob. I usually do it in a grill pan and roast for about five minutes. Allow to cool.
Mix cooled corn, tomatoes, beans, and onions in a medium bowl
Squeeze the juice from the lime and drizzle on top.
Drizzle oil and vinegar to taste - once around the bowl is usually enough oil for me and about a tablespoon of vinegar (but I never measure.)
Mix gently and add sea salt to taste
Top with avocado immediately before serving
If you want some some protein, add chicken strips, shrimp or tofu.
