Overcook the sweet potatoes. Either bake them in foil, steam, roast (I'm sure roasting would give them an even nicer flavour) or bbq. Get them overcooked so they are really soft and you can mash them with a fork.

Add applesauce (we used an Organics Applesauce snack cup. I think it might have been sweetened, so you may need to add some sugar to tast if you use unsweetened).

Add Cinnamon.

Mash it all together with a fork, or use a blender for a smoother texture and serve.
