In a pan, melt “butter.” Add apples, no-calorie sweetener, cinnamon, and nutmeg and sautee until apples are considerably softened. Set aside.
In a dry pan, toast the hazelnuts and walnuts until browned.
In a blender or food processor, combine cereal, remaining sweetener and nuts until a crumb mixture forms.
Place apples in a casserole dish (I used a 9 x 13). Top with crumb mixture and bake at 350 for about 30 minutes or until apple mixture is bubbling up through openings in the crumb AND crumb mixture is brown.
