So I made this by accident when it turned out I had no spinach.
You fry a load of onion with some garlic and cumin and sliced chorizo. Then you add the spinach and some cinnamon and cook through. This is what you are supposed to get and it is nice.
I had no garlic today and so just fried the other things. Then upon realising I had no spinach I had the bright idea of making the onions and sausage a sandwhich filling. Add some feta chunks and it's really delicious and I think better than what I had intended to make.
I did go to the supermarket after though. Because when your house contains nothing but onions, feta, and a chorizo sausage this is when you know it is grocery time.
