Heat 1T olive oil in a medium saute pan over medium heat. Add pears, sugar, and cinnamon and stir until coated. Cook pears for 5-7 minutes, stirring occasionally. Pears should be sweet but still firm. Remove from heat and set aside. Make vinaigrette by combining oil, vinegar, and salt and pepper (to taste) in a blender and pulsing until combined. Alternately, pour vinegar into a small nonreactive bowl and slowly drizzle olive oil into the vinegar, whisking while you pour, until blended. Season with salt and pepper to taste. Toss greens with vinaigrette and top with remaining ingredients. Serve immediately.
