This fresh blueberry salad is perfect for a backyard cookout or poolside party. Pair it with grilled chicken, pork chops, or fish—or serve it up with a smorgasbord of classic summer sides like potato salad and cole slaw.  The blueberries are the stars here, so select the best ones you can find. Look for ripe berries that have a dark blue color and a juicy "pop" when eaten. If you can't find fresh berries, you can substitute frozen ones in a pinch. Simply thaw the blueberries under room temperature water, then pat dry with paper towels.
