Steam the pumpkin till it is soft.
Take it out of the steamer and let it cool.
When it is cool, scoop out the pumpkin from the skin.
Now put the pumpkin in a bowl.
Mash it up.
Mix in the tahini.
Then mix in the water and Spike seasoning to taste.
Put it into a small pot and warm it up.
You can now sprinkle your choice of herbs or spices on it if you choose. Parsley or coriander add a nice touch.
Now serve your pumpkin sauce on top of vegetables or a grain.
