Preheat oven to 375°. Core pears from bottom, leaving stems intact. Peel pears; cut in half vertically. Cut 1/4 in. from bottoms to level if necessary. Place in an ungreased 13x9-in. baking dish.
Place ginger ale and honey in a small saucepan. Cook and stir until combined; spoon over pears. Bake, uncovered, 25-30 minutes or until tender, basting occasionally.
With a slotted spoon, remove pears to individual serving dishes. Transfer pan juices to a small saucepan; stir in ginger. Cook and stir over medium heat 5-8 minutes or until heated through. Spoon over pears; sprinkle with pecans.
