Crostini with Grilled Sweet Onions and Blue Cheese

Place onion wedges, cut sides up, on a rimmed baking sheet. Drizzle evenly with 2 tablespoons vinegar and oil; sprinkle evenly with salt and pepper.

Preheat a gas grill to medium (350°F to 400°F) on one side, or push hot coals to one side of a charcoal grill. Place onion wedges, cut sides up, on oiled grates over unlit side of grill. Grill, covered, 20 minutes. Turn onions onto one cut side; grill, covered, until grill marks form, about 10 minutes. Turn onions onto remaining cut side; grill, covered, until tender, about 10 minutes. Remove from heat.
