Preheat oven to 325F. Toss cheese with 1 tsp. of the dressing in small bowl.
Place in small resealable plastic bag.
Add peanuts; seal bag. Shake to evenly coat cheese with the peanuts; place on ungreased baking sheet. Reserve any remaining peanuts in bag.
Bake 7 to 8 min. or until cheese is slightly softened. Meanwhile, toss greens with remaining dressing and reserved peanuts. Divide evenly between two salad plates.
Arrange four pear slices on each salad; top with one of the warm cheese wedges.
