Spaghetti with pumpkin and smoked ham sauce

Ingredients for two:
160 g corn flour spaghetti
100 g pumpkin pulp (peeled and without seeds)
100 g speck (type of Italian smoked ham)
50 ml soy milk
50 ml soy yogurt
1 tablespoon marjoram
1 fourth of a medium onion
salt
extra virgin olive oil
1 tablespoon tomato paste
Parmesan cheese

This is one of fast and tasty sauce for pasta that I create , as often happens, with that I find in the fridge.

Preparation:
I cut the onion up and I sweet it in a pan with a drizzle of oil, then I add thinly sliced pumpkin and I let it stew for ten minutes, adding some tablespoons of warm water.
Later I add speck strips, marjoram and I let them flavour for other 5 minutes, then I add soy milk and yogurt and a tablespoon of tomato paste.
I let the sauce cook for 10 minutes more up becoming a cream.
I pour the spaghetti in a pan with boiling water let them cooking the time indicated in the pack (usually 10-11 minutes).
Two minuted before the complete cooking I drain the spaghetti.
I pour pasta in a pan and I cook it until is creamy for the remaining cooking minutes.
I serve spaghetti with a sprinkle of grated Parmesan cheese.

The nice thing about cooking, I can always make something different and unique and if I'm lucky even good.
