Rinse and wash the fresh cranberries, then pierce each with a toothpick. Then throw the cranberries into the baking dish, evenly among the pear slices.
In a bowl, mix the oats, brown sugar (you may add more than 1/4 cup if you desire), cinnamon, nutmeg and oil together.
Sprinkle this oats combination mixture over the pear slices and cranberries in the baking dish.
Feel free to double or triple the recipe if you like. Since the ripened pears are already sweet, you don’t really need to add too much additional sugar to sweeten the dish. So adjust the sweetness level to what you prefer by the amount of brown sugar (or maple syrup or agave nectar) you add. This crisp keeps for a few days in the refrigerator and tastes delicious cold too!
