Unwrap and place 1/2 of the sandwiches in a 9x13 inch pan. Cut a sandwich, if needed to fill the pan. Layer 1/2 the fudge or chocolate sauce over the sandwiches. Top with 1/2 the Cool Whip. Sprinkle 1/2 the nuts over the Cool Whip.
Repeat the first layer. Cover and freeze. Can be frozen for up to 2months.
You may add sliced bananas, sliced strawberries or any fruit you like over the chocolate layers. I add sliced bananas.
