Cut pears in half lengthwise; remove cores. Brush pears with lemon juice. In a small bowl, combine the brown sugar, butter, flour, cinnamon and salt; stir in pecans. Spoon into pears; place in a 4-qt. slow cooker.
Optional: drizzle honey over pears. Cover and cook on low for 2-3 hours or until pears are tender. Serve warm.
