Preparation of Dressing: Begin by assembling the dressing. In a small mixing bowl, combine the extra-virgin olive oil, balsamic vinegar, honey, and Dijon mustard. Whisk these ingredients vigorously until the mixture is thoroughly emulsified. Season with salt and pepper according to taste preferences. This dressing will serve as the cohesive element for the salad, enhancing the overall flavor profile.
Salad Assembly: In a large salad bowl, layer the fresh arugula as the base. Arrange the sliced peaches, crumbled goat cheese (or feta), toasted pecans (or walnuts), and thinly sliced red onion atop the arugula. Should you opt to include basil, sprinkle it over the other ingredients now, distributing it evenly.
Incorporating the Dressing: Drizzle the prepared dressing over the assembled ingredients in the salad bowl. Using salad tongs or gently with your hands, toss the salad to ensure an even coating of the dressing on all components. Care should be taken to mix the salad lightly to prevent bruising the arugula or damaging the peaches.
Serving: Immediately transfer the tossed salad to a serving platter or distribute among individual plates. This prompt serving ensures that the arugula retains its crisp texture and the peaches maintain their structural integrity, providing an optimal eating experience.
