Base:

Preheat oven to 350 degrees F.

Peel, core, and cut pears and apples into nice chunks. 

Toss the fruit in a bowl with orange zest, juices, sugar, flour, cinnamon, and nutmeg. 

Pour into a 9 X 12 X 2-inch oval baking dish.

Topping:

Combine flour, sugars, salt, oatmeal, and butter in the bowl of an electric mixer fitted with the paddle attachment. Mix on low speed for 1 minute, until the mixture is in large crumbles. 

Sprinkle evenly over fruit, covering the fruit completely.

Place the baking dish on a sheet pan and bake for 50 minutes to 1 hour, until the top is brown and the fruit is bubbly. Serve warm.
