Preheat your grill or grill pan to medium temperature.
Lightly coat the cut sides of the peach halves with olive oil and season with a pinch of salt.
Place the peaches on the grill, cut-side down, and cook for approximately 4-5 minutes until grill marks appear and they soften slightly.
Remove the peaches from the grill and set aside to cool.
In a separate bowl, combine balsamic vinegar, honey, and olive oil, whisking until smooth.
Adjust seasoning with salt and pepper to taste.
In a large serving bowl, mix the assorted greens with half of the honey-balsamic dressing.
Layer the grilled peaches over the greens, then break the creamy cheese into chunks and distribute it across the salad.
Top with toasted walnuts and crumbled goat cheese.
Drizzle the remaining dressing over the salad and serve immediately.
