01 - In a small bowl or jar, whisk together the olive oil, balsamic vinegar, honey, Dijon mustard, salt, and pepper until smooth and emulsified. Set aside until ready to dress the salad.
02 - In a large salad bowl, combine the mixed salad greens, fresh blueberries, and thinly sliced peaches. Add half of the crumbled feta cheese and distribute evenly.
03 - Drizzle the prepared vinaigrette evenly over the salad. Using salad tongs, gently toss to coat all ingredients lightly with dressing without bruising the delicate fruits.
04 - Sprinkle the remaining feta cheese and toasted nuts over the top of the salad. Garnish with additional fresh blueberries if desired.
05 - Serve the salad right away while the greens remain crisp and the fruit is fresh. Optionally finish with a fresh grind of black pepper just before serving.
