Combine ¼ c. sugar and pecans in a small skillet over medium heat.  Stir gently until sugar has melted and pecans have caramelized 4-6 minutes.  Transfer nuts to wax paper.

     Whisk together oil, vinegar, remaining 1½ t. sugar, mustard, garlic, salt, and pepper in a small bowl to make dressing.

     Layer lettuce, pears, cheese, and green onions in a large serving bowl.  Just before serving, pour dressing over salad, sprinkle with pecans, and then toss.
