What to do:
Oil grill grates, then preheat grill to medium high heat. Working in batches, grill peppers, onions, zucchini and squash, flipping once, until just charred in parts and tender, 6 to 8 minutes total; transfer to a large platter as done. Set aside to let cool before cutting into bite-size pieces.
In a large bowl, combine grilled vegetables, garlic, vinegar, oil, basil, chickpeas, salt (if necessary) and pepper. Garnish with parmesan and serve immediately or cover and chill until ready to serve.
