Preheat oven to 350 F. Spray a 9 x 5” loaf pan with nonstick cooking spray.
Mix together the chopped apples, brown sugar, walnuts, and cinnamon until well combined.
Using a pair of clean kitchen scissors, cut each roll into thirds.
Place 12 small roll pieces in the bottom of the loaf pan. Drizzle about a third of the melted butter on top of the roll pieces. Then top with a third of the apple mixture. Repeat two more times until all ingredients have been used.
Let rise for about an hour, or until rolls have doubled in size.
Bake 30 to 50 minutes, until tops are golden brown and the middle rolls are done.
