Grilled Peach & Burrata Salad

1 Make the dressing: Whisk together olive oil, apple cider vinegar, honey, Dijon, salt and pepper.
2 Grill the peaches: Heat a grill or grill pan over medium-high heat. Lightly brush the cut sides of the peaches with olive oil. Grill cut-side down for 2–3 minutes, until grill marks form and the peaches are slightly softened. Flip and grill for another minute.
3 Build the salad: Add arugula and tomatoes to a large bowl. Toss with about half of the dressing.
4 Add the good stuff: Arrange the grilled peaches and torn burrata over the greens. Sprinkle with pistachios and add prosciutto, if using.
5 Finish: Drizzle with the remaining dressing and serve immediately.
