For the Filling
Tip: select pears that are ripe, but not too soft. If your pears are too soft, throw an apple or two in to help ensure you have a variety of textures in your fruit filling.
For the Crumble Topping
Bake for 30 minutes, or until the oat topping is browned and filling juices are bubbling. Tip: If you like a bit of a toasty flavor, broil for up to 1 minute.
