Put the wholewheat spaghetti on to boil for 15 minutes
While pasta is cooking, water sautee the onion and mushrooms until soft.
Start pan frying the chorizo with a little spray oil. I cooked my own in the same pan as the onions and mushrooms so some of the flavour transferred.
Add crushed chillis (as much as to your liking of heat) and garlic powder to the onions and mushrooms, and cook for another minute.
Add the spinach and allow to wilt. Add the nutritional yeast and mix through, then take off the eat and add the creme fraiche.
Drain the spaghetti, and mix with the creamy mixture.
