In a large bowl, combine pears and cranberries; drizzle with lemon juice. Combine the sugar, flour, lemon zest, cinnamon and nutmeg; stir into pear mixture. Transfer to an 8-in. square baking dish coated with cooking spray.
For topping, in a small bowl, combine the flour, oats, brown sugar, flax and salt. Stir in butter and oil until crumbly. Sprinkle over fruit mixture. Bake at 350° until topping is golden brown and fruit is tender, 35-40 minutes.
