Put the couscous, coconut milk and yoghurt in a sealable container and mix well. Now add the pumpkin pulp and refrigerate overnight.
The next morning just take the container out of the refrigerator and then you can eat.
Note: For the pumpkin sauce, cut a pumpkin (I always use Hokkaido) in half and remove the seeds with a spoon. Bake in a preheated oven at 180 degrees for about 40 minutes
