Follow roasting directions on package. Let stand 15 minutes before carving.
Meanwhile, combine pears, garlic, wine and brown sugar in medium saucepan. Bring to a simmer over medium-high heat then reduce to medium-low. Cook 25 minutes, or until pears are very tender and most of wine has evaporated. Place pear mixture into food processor container fitted with steel blade; process until smooth. With machine running, slowly add remaining 1/4 cup olive oil through feed tube to make a smooth and creamy puree. Pour into medium bowl. Stir in lemon juice, salt and pepper. Serve at room temperature or refrigerate until ready to serve.
