Place 20 frozen Rhodes rolls in a bundt pan sprayed with cooking spray.  Pour 1 stick melted butter over the rolls.  Combine one small vanilla pudding mix (cooked kind, not instant), 1/2 cup brown sugar, and 1/2 cup chopped pecans or walnuts.  Sprinkle over rolls.  Leave out overnight. 
In the morning, bake at 350 for 30 minutes.  Put serving plate on top and invert immediately.
