This hearty soup filled with greens and savoury chorizo sausage is a favourite for many. Try using different greens to change up the flavour; rapini, collards or spinach all would work really well.
In a large soup pot, heat oil over medium heat and saute sausages until browned. Remove to bowl.
Return pot to heat and cook onion, celery, carrot, garlic and hot pepper flakes for about 5 minutes or until softened. Stir in kale, Swiss chard and potatoes to coat. Pour in broth and bay leaves; bring to a boil. Return sausage to pot and simmer for about 20 minutes or until potato and greens are tender.
