Cut the peaches in half and remove pits. Brush the peaches with honey. Brush grill with olive oil and heat to medium-high heat.

Place the peaches on the grill, cut side down. Grill the peaches until they are softened and grill marks appear, about 4 to 5 minutes.

Let the peaches cool to room temperature and then slice. Arrange the peach slices over a bed of mixed salad greens.

Top salad with crumbled blue cheese, pecans, and red onion slices. Drizzle salad with balsamic dressing, or dressing of your choice.
