- Preheat oven to 350°F (180°C). Place prosciutto on a baking sheet and bake on middle rack of oven until golden and firm, about 12 min. Let cool then crumble.
- In a large bowl, whisk together vinegar, syrup, mustard and oil. Season with salt and pepper. Add arugula, Parmesan, pear and prosciutto and gently toss to combine. Serve immediately.
Crisp the prosciutto in the morning and keep it refrigerated in an air-tight container.
