Russian Berry Pie is always a favorite amongst the Scouts. To make it you line a dutch oven with tin foil, put a can of blue berry pie filling in.  Sprinkle some cinnamon on top, then put a can of cherry pie filling in, sprinkle some more cinnamon, then a can of crushed pineapple in, sprinkle some more cinnamon, then a can of apple pie filling, and sprinkle more cinnamon.  Then you put a box of yellow cake mix over the top of all that, then cut up a stick of butter into thin slices and place them over the cake mix.  Then you put a layer of mini-marshmellows over that.
