Grill corn on medium heat until lightly charred. Preheat the oven to 500°F. Line a large baking sheet with foil and place the tomatoes and peppers skin-side up on the sheet. Bake for about 20 minutes or until vegetables are blistered.
Once roasted, place the peppers and tomatoes in a large plastic bag and seal for 10 minutes to loosen skins. Peel the tomatoes and peppers, remove and discard the pepper seeds, and chop. Add all remaining ingredients to the black bean mixture and stir to combine.
