Heat a large soup pot with a bit of coconut oil and bake the onions until translucent. Add the garlic and the peppers and bake for a minute or two. Add the chopped chipotle, the tomato cubes and the stock and bring to a boil.
Leave to simmer for about 30 minutesn or until the bell peppers are nice and soft. Puree the soup with a stick blender.
In the meantime you fry the chorizo bits in a dry frying pan until crispy. Leave to drain on kitchen paper and chop smaller after cooled a bit.
Serve the soup with the chopped chorizo and the feta. Add the soy beans if using.
