Grease a 9x13 cake pan or the slightly smaller one works well too.
Cut the cinnamon rolls into quarters and place in the bottom ofthe pan.
Spoon over the roll pieces with the can of pie filling.
Sprinkle with nuts.
Bake at 350 degrees for 30 minutes.
Put the frosting from the package that comes with the cinnamon rolls into a ziplock baggie and cut a corner off and drizzle over the cooled cake!
