Apple Crisp - Gluten-free

Preheat oven to 350F. Grease large 12x15" baking pan.
Cover the bottom of pan with apple slices. ( Any kind of apple is fine. I use apples from my garden)
Sprinkle 3/4 cup granulated sugar on apples. Set aside.
Crumb Topping
1 and 1/2 cups of packed brown sugar
1 cup Celimix rice bread mix
4 cups gluten free rolled oats
1 cup margarine or butter ( I use soft margarine)
Combine sugar, rice bread mix and rolled oats in large mixing bowl. Using hands, crumble in the margarine making it into a crumbly mixture.
Place on top of apples.
Bake 30 minutes or until done and crumbs are nicely browned.
Recipe may be halved as this recipe does make a large pan of Apple Crisp.
