Slice pears into ¼ inch thick slices and drizzle with olive oil. Don't use too much olive oil, just enough to lightly coat the pears so they don't stick to the grill/pan.
Pre-heat the grill or grill pan. Grill the pears over med-high heat for about 20 seconds on each side. You don't need to fully cook the pears. You just want to grill them long enough to warm them up and get grill marks on them.
Once the pears are all grilled, set them aside and make the salad.
In a large serving dish or plate, assemble the salad:Place the arugula into the bowl or on a serving tray, top with Proscuitto, goat cheese, walnuts, pears, and drizzle lightly with remaining olive oil and honey. I like to serve on a serving tray on a bed of the arugula topped with alternating pears, Proscuitto and goat cheese.
