Blend butter, brown sugar, flour, oatmeal, cinnamon and nutmeg until crumbly and spread over the apples. Bake for 30-35 minutes or until apples are tender and topping is golden brown.
TIP: If peeling your own apples, you can keep them from getting brown by putting them in a mixture of 1/4 cup lemon juice to 1 quart of cold water.
