For Oatmeal Layer: In a large bowl, combine shortening and sugar until light and fluffy.  Add applesauce and vanilla and thoroughly combine.  In a small separate bowl, combine flour, baking soda, and salt.  Add dry mix to wet mix and stir well.  Stir in oats.  Reserve half for topping.  Spread the rest into a greased 11x7 or 8x8 baking dish.

For Fudge Layer:  In a microwave safe bowl, combine the chocolate chips and margarine.  Heat for 30-45 seconds until just melted.  Add 1 tbsp. water and stir until combined.  Combine flour and sugar in a small bowl.  Add chocolate mixture to flour mixture and combine.  Spread fudge layer over the oatmeal layer.

Sprinkle top with reserved oatmeal mixture and spread over fudge layer.  Bake at 350 for 20-25 minutes or until lightly browned.  Cool before cutting into squares.
