1. Preheat the oven to 400°F. 2. In a medium bowl, toss the pears, sugar, and butter. Arrange the pears in a single layer in a baking sheet. Bake, turning once, until the pears are barely tender, 10—15 minutes. 3. Dry roast the pine nuts in a skillet for 5 minutes, until toasty brown. Remove from the heat and set aside. 4. In a large salad bowl, prepare the dressing by whisking together the oil, vinegar, garlic, salt, pepper, mustard, and maple syrup. Add the arugula or salad greens and toss to coat. 5. Divide the salad onto four chilled plates. Arrange the roasted pears in a fan around the center, and sprinkle with the cranberries, Parmesan cheese, and pine nuts. Scatter with petals from the calendula blossoms.
